Смотрел я как то их исходники и увидел такую лажу:

vi +114 os-registry.c

/*
* Option: EnableALiAGP
*
* Description:
*
* Some ALi chipsets (ALi1541, ALi1647) are known to cause severe system
* stability problems with AGP enabled. To avoid lockups, we disable AGP
* on systems with these chipsets by default. It appears that updating the
* system BIOS and using recent versions of the kernel AGP Gart driver can
* make such systems much more stable. If you own a system with one of the
* aforementioned chipsets and had it working reasonably well previously,
* or if you want to experiment with BIOS and AGPGART revisions, you can
* re-enable AGP support by setting this option to 1.
*
* Possible Values:
*
*  0: disable AGP on Ali1541 and ALi1647 (default)
*  1: enable  AGP on Ali1541 and ALi1647

Так что попробуй запустить дрова для вилюхи со встроенным в ядро agpgart'ом .
Может поможет.
Делается так:
В секции XF86Config-4 добовляен :
NvAGP "0" // вырубить agp
NvAGP "1" // юзать nvid'овский
NvAGP "2" // юзать встроеный
NvAGP "3" // сначала попробовать нвидовский а затем встроенный
