Soren, can you give the current DRM tree a try or apply the patch in 
http://cgit.freedesktop.org/mesa/drm/commit/?id=cb33133ef354b77a8cf06b16ce95a0babbe8bc6f?  
I'm hoping it'll fix the one machine that had a problem and not break the 
other. :)  I tested it on my new 855 machine and it fixes things here...

Thanks,
Jesse
