>Description:
Trying to enable dri/drm support on VIA KT400/400a/600 based
chipset will lock up the machine, since the agp driver use
the wrong hardware register (AGPv2, instead of AGPv3).
>How-To-Repeat:
Load drm module for your card, enable dri in XF86Config, run X.
If you're using AGP 8X card (Radeon 9200 for example), either
your machine will come to abrupt halt, or suddenly become
sluggish.
>Fix:
Apply this patch. Rebuild kernel/modules.
