Don't know if this helps to answer your question, but the below section is cut and pasted from the SF Match timeline website...Good luck, as they should be announcing if there are any vacancies tomorrow.
JAN 25, 2006
Vacancies Released Any post-match vacancies which remain after the match will be announced on our Vacancy Information System. We only list vacancies of programs which have indicated that they will accept applications for their unfilled positions.
Applicants who did not match may begin applying to these positions by negotiating directly with the programs regarding any documentation that they require. If the programs ask you to forward your CAS file, use our Applying To Vacancies Form to request the distribution. There is a fee for this service.
