This time it's really supposed to be a quickie, so people who can, please 
check it out, and we'll make the real 2.6.11 asap.

radeonfb oopses on intel.
Havent checked yet when it started with it.

Hrm... that's totally bogus. What machine is this ?

Some i386 box with radeon 7000.

It seem to detect the flat panel incorrectly, or the EDID data is bogus,
maybe that's wrecking something in the new modelist management in
fbdev ? It might be causing us to use a bogus mode that itself casues
atyfb to crash. Tried forcing a mode ?

is bitstart incorrect or is the thing just not (yet) mapped?
