Radeon video in PowerBook G4 800

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.

You may wish to try http://www.unixbox.com/~ajoshi/radeon_drv.o.gz, unzip
and replace your /usr/X11R6/lib/modules/drivers/radeon_drv.o with it.
That should get X working.  If you cannot get the 0.1.5 patch from the
archives still, let me know and i'll send u a copy.

Well I did get the 0.1.5 patch and I applied it. It did not seem
to help any. I had to merge things by hand at some parts since
the benh kernel did already have some stuff in there. 

Can I get a copy of the 0.1.5 instead of a patch so we can be sure
we are on the same page.

Ben, do you have any an email of someone that has it working
so we can try to compare some things?
