The story was that the Time Lords revived The Master, so that he could serve as a 'last resort' in the final war with the Daleks. That never came about, though, so his identity was kept suppressed, and he lived on in the distant future as 'Professor Yana'.
The destruction of Gallifrey would seem to be a setback to reviving The Doctor again, but thanks to the nifty miracle of time travel, anything's possible - since the Time Lords were killed, but not erased from history entirely.
Professor Yana regenerated into (SPOILER)Howard Saxon. The Time Lords revived him into the Professor Yana incarnation, but he regenerated after that, so clearly he found a new way around the regeneration limit.
