SR22 pilot believes he may have entered a firefighting tfr while on base and final for runway 25 at ...

Narrative:

There was a firefighting tfr in the vicinity of colfax; ca that had been in effect [for several days]. The western edge of the tfr was just off the eastern end of runway 25 at aun; necessitating landing on runway 7; even though the winds favored 25. I confirmed the tfr was still in effect using a ground-based pc prior to takeoff. In the air; however; it wasn't visible on my mfd even though other tfrs in the area were; (the mfd uses xm satellite weather as its tfr data source). I contacted FSS in the air and they confirmed the tfr was still in effect; though we didn't discuss the precise boundaries. As I approached aun I monitored traffic on the CTAF and everyone was using 25. When I asked about the tfr I was told it had moved far enough away from 25 to allow its use. Because of this; and because other traffic was using 25; I chose to land on 25. Because I couldn't see the tfr; though; it's possible I briefly penetrated it while on my base and final approach legs.
