I've recompiled everything (kernel + drm-modules), so we can rule out
the gcc version problem.
At least, I've got something new : I compiled drm-modules from
gatos.sf.net, today's cvs state. I've got exactly the same behavior
(black screen, X eating 99.99% of CPU), _but_ the X log says
everything is normal (no more drmSetBusId error), including dri.
The new log is to be found here :
Any further idea ?
