For certain, the following have no regional preferences.
CCOM (chicago college of osteopathic med)
AZCOM (arizona " ")
PCOM (philadelphia " ")
Nova (in florida)
LECOM (lake erie " ")
Kirksville (in missouri)
UHSCOM (University Health Sci Col of Osteo)
DMU (Des Moines University)
Touro
Western
NJCOM? (new jersey: I'm a little unsure on this one, however a friend of mine, fellow michigander, will be attending there in the fall.)
Schools with definite regional pref (though they do except a small number of out of staters) include: MSUCOM, WVCOM, TCOM, Pikeville (they did grant me an interview, though, but I believe that to be a result of some mission work I did in the region and noted in my personal statement).
Unsure on the rest: New England COM, Oklahoma, NYCOM, and Ohio.
Your best bet, is to check out USNews and World Report.

They provide stats on the entrance numbers for in-state and out-of-state applicants.
