DRM & X.Org 6.8.0 oops

[Hagbard Celine]

Hello,

I've exactly the same machine as the one in the post (ASUS P4P800-VM +
P4 2.8HT (Prescott)) and the same 2.6.8.1 kernel and Xorg 6.7.99.904
(gentoo).

I use the i915 drm kernel module compiled from the Xorg sources and I
experience no problem at all. It's stable since days and I've played
also few hours of armagetron (which I suppose use a lot of drm).
