Note: this is a hand edited patch as the AGP texturing patch is in the diff
too (so there will be fuzz). /Every/ dri seg I got (once I was able to run
quakeforge under gdb) involved .prev being 255 (remember: prev is an unsigned
char). I don't feel I've done enough testing, but with this patch I have had
niether crash nor texture corruption.
I will personally vouch for Ralf's AGP patch. It took my G200 from a lump of
silicon to a card that can play quakeforge and quake3 at acceptable rates
(generally over 20fps (hey, it's a G200:)).
