It is my understanding that you cannot do any of the boarded fellowships without being board-eligible (in either AP, CP, or AP/CP depending on the fellowship).
If you can meet the requirements for AP certification by the end of your third year, then I say take the fellowship. That's of course if you are truly interested in dermatopathology. As for whether you can come back after the fellowship to finish CP, and how long it would take, you are going to need to talk to your program director to find that out. A good program director will do everything to support you, within the rules and as long as it doesn't adversely affect the residency program. If you are going to be leaving an unfilled residency position in your program for 2008 then you might have difficulty.
No offense but you are incorrect. The ACGME accredits these fellowships and there is no such rule requiring you to be "board-eligible" to enter all accredited fellowships. In fact the American Board of Pathology does not even sanction the use of the term "board eligible". The eligibility criteria vary according to the fellowship..

I have cut and pasted the eligibility requirements below:
Cytopathology

pathology or 18 months of clinical pathology."
Dermatopathology
"Eligibility Criteria
The program director must comply with the criteria for fellow eligibility as

Anatomic Pathology/Clinical Pathology (AP/CP-4), or Dermatology."
Hematopathology
"Eligibility Criteria
1. The program director must comply with the criteria for fellow eligibility
as specified in the Institutional Requirements.
2. Fellows should have completed at least two years of training in an ACGMEaccredited
pathology residency, or be certified in another specialty by a

Blood Banking
"Eligibility Criteria

Chemical Pathology
"Eligibility Criteria

specified in the Institutional Requirements. Fellows must have completed at least
two years of training in an ACGME-accredited pathology residency, which must include
at least 18 months of clinical pathology, prior to admission to the program."

Pediatric Pathology
Eligibility Criteria
The program director must comply with the criteria for fellow eligibility as

two years of training in an ACGME-accredited pathology residency prior to
appointment to a pediatric pathology program."
Molecular Genetic Pathology
"Eligibility Criteria
1. The program director must comply with the criteria for fellow eligibility as specified in the Institutional Requirements.
2. MGP fellows should have completed training in an ACGME accredited residency in either Medical Genetics or Pathology, or be a physician certified by the American Board of Medical Genetics"
Medical Microbiology
Programs will be accredited to offer one year of graduate medical education in medical
microbiology following the completion of an ACGME-accredited residency in Anatomic
Pathology and Clinical Pathology, Anatomic Pathology, or Clinical Pathology, or
completion of an ACGME-accredited residency in another primary medical specialty
and completion of an ACGME-accredited fellowship in infectious diseases.
I was incorrect to post the idea of going back for one additional year of CP after the dermpath fellowship. Since dermpath requires AP-3 or AP/CP-4 prior to doing the fellowship, it looks like you would have to do two years of CP after the dermpath fellowship in order to be able to sit for the CP board exam.
It is interesting to me that it appears that ABMS board certified OB/GYNs, Anesthesiologists, Surgeons, and Pediatricians for example are able to meet the requirements to hematopathology, blood banking, and neuropathology fellowships.
However the requirements to sit for the board exams are a bit different. See ABP website:

Blood Banking
For diplomates of the American Boards of Anesthesiology, Internal Medicine, Obstetrics/Gynecology, Pediatrics, Surgery, Orthopedic Surgery, Plastic Surgery, Colon and Rectal Surgery, Neurological Surgery, and Thoracic Surgery: 1 full year of additional training in blood banking/transfusion medicine in a program accredited for such training by the ACGME.
Hematopathology
6a. For applicants who hold any primary certificate in pathology or have a primary certificate plus a subspecialty certificate in hematology from another member medical specialty board of the ABMS: 1 full year of additional training in hematology (pathology) in a program accredited for such training by the ACGME
6b. For applicants, other than those described in 6a, who are certified by another member medical specialty board of the ABMS: 2 years of full time training in hematology (pathology) including 1 year as a trainee in a program accredited for such training by the ACGME and one additional year in hematology acceptable to the ABP. ABP approval for the additional year should be obtained before the individual begins the additional year.
Neuropathology
For applicants who are certified in clinical pathology or are certified by another member medical specialty board of the ABMS:
(1) 1 full year of approved training in anatomic pathology in a program accredited for such training by the ACGME and
(2) 2 full years of additional training in neuropathology in a program accredited for such training by the ACGME
