The patches in question are attached. I thought I had a cleaned up 
version somewhere, but it doesn't really matter much either way since it 
needs to be cleaned up again for Mario's work anyway (not using 
MESA_drm_image, I suppose -- I haven't looked at this in quite some 
time). But with these patches it used to work at one point :)
