Ko god da je imao problem sa podizanjem OpenGL drivera treba da proveri sledece.
Greshka je bila tipa cannot int AGP a dmesg je prijavljivao detaljni probelem u mtrr-uNajme kad se otkuca cat /proc/mtrr videce se i zashto..totalna nebuloza u vidu:
reg00: base=0x00000000 ( 0MB), size=984064MB: write-back, count=1size=984064MB…mashala…: )
detalji su na:

#!/bin/sh
# Fixup /proc/mtrr

# chkconfig: 12345 0 99
# description: Fixup /proc/mtrr
#
# Save this file as /etc/init.d/mtrrfixup and
# use “chkconfig –add mtrrfixup”
# to have this script run by init when the system starts.
#
# The default mtrr table after boot looks like the following:
# reg00: base=0xd8000000 (3456MB), size= 128MB: uncachable, count=1
# reg01: base=0xe0000000 (3584MB), size= 512MB: uncachable, count=1
# reg02: base=0x00000000 ( 0MB), size=4096MB: write-back, count=1
# reg03: base=0x100000000 (4096MB), size= 512MB: write-back, count=1
# reg04: base=0x120000000 (4608MB), size= 128MB: write-back, count=1
# reg05: base=0xd7f80000 (3455MB), size= 512KB: uncachable, count=1
#
# The main problem is entry 1, which covers
# the AGP aperature and Video Card memory.
# Being present and uncachable, it prevents
# the fglrx driver module from using/creating a
# write-combined region for the video card.
# The second problem is entry 2, covering all
# our ram, which prevents us from creating
# any new sections which aren’t uncachable.
#
# We have a maximum of 7 mtrr registers.
# All sizes must be a power of two.
# The start and end of any page must
# have the same ‘upper bits’.# First remove all existing values…
# Order matters – wrong order locks system hard!

Posle ovoga je uspeo da se podigne X sa ATi-jevim OpenGL-om a glrxgeras konachno ide na 4000+ fps-a.
Naravno neizbezno proban quake 4 i radi.
Ali izgleda da problem nije vezan za distro vec je tu neshto zeznuto sa pogreshno ochitavanjem BIOS-a na nekim plochama.
Pazi kako sam ja mogao da zakljuchim izgleda da se probelm javlja kod nekih matichnih plocha. Treba probati, al’ ako imash ovakvih problema kao shto sam ih ja imao onda je to to. Meni se problem izgleda javljao i na Mandrivi 2006 pa sam pomislio da je do distro i preshao na suse 10.0 kad ono isto.
cat /proc/mtrr i odmah se vidi da li imash problema
a vidi se i sa dmesg komandom.Samo patch se nameshta jednostavno al’ mora da se pazi na kolichinu rama u mashini i na grafici. Sve je u HEX vrednostima ..pa mora malo rachuna…al’ ima i tabela.
isto bi ti se desilo i sa fedorom 4
reg00: base=0x00000000 ( 0MB), size=983552MB: write-back, count=1
Verovatno..totalna besmislica. Mozda neko probao nnajnovije 8.21.7 drivere..? Kakvo poboljshanje oni donose poshto je q4 ochajan sa 8.20
