Fonts regression on r200, they are good in 7.3<=. This can be seen in q3 based games and doom3 also. I can only noticed this on low resolution like 640x480 and 800x600, but not at 1024x768 which is my desktop resolution. Again, in 7.3<= fonts are proper at every resolutions.

Confirmed. Looks like nearest filtering gets used instead of bilinear (with high enough resolution it just doesn't matter much there). git-bisect tells me it's 42ce7900865f857ff6fa07a3e0d1d910426e3633 ("mesa: refactor glTexParameter code").
I'll look into it.

Fixed in master (ebc1478e501d43e0de54e7b6c3edfbc81d7d20c6) and mesa_7_4_branch (7be149cfd131c0b3f7d4337bb83e6fba5f563bf9).

 Thanks, it is fixed. With that commits you have fixed dynamic lighting problem also (bug #20965).
