Ok, CVS is the really interesting one. Michel, did you ever commit
the fix of SURFACE_CNTL ? That should fix the colors at least on
the main aperture

That is probably the SURFACE_CNTL problem.

Typical with offb, X doesn't properly restore the radeon state to offb
graphics mode it seems.

Can you tell me more about the "crash" ? The benh-devel rsync should
work just fine on this config with more radeonfb fixes. Framebuffer
should work too without video=ofonly. Can you try my latest devel
kernel and tell me ? If it boots but with no framebuffer, can you
try to capture the boot log to a file and send it to me.
(Please, let's continue the kernel related discussion separately and
offlist)
