I'd be more than happy to mark it as "toasted" and go on, but then I wouldn't be able to use it with WindowsXP (never had a crash there) and neither with Xorg 1.6 (that works but because as you said the driver hits less frequently the cache).

Has Intel ever released the WindowsXP driver sources? Yes, I know..just dreaming..

Is there any other way that could explain the GTT<->CPU bug?

I'll add my Tested-By with next patch, since this one doesn't seem to be in-sync with latest drm-intel
