Radeon video in PowerBook G4 800

I am having problems with the radeon fb driver in BenH's 2.4.19-pre10
kernel. When it boots I get a strange grayish red blob that covers most
of the screen starting from the bottom right side.

I tried Xfree 4.20 and saw a similar effect.

Here is a dump from the init with DEBUG turned on in the driver.

The BenH kernel has some fixes from the 0.1.4 radeon driver and
I have not been able to get the 0.1.5 patch from the archieves 
to try.
