Hi,

I have a weird error with my PowerBook G4, which
has a radeon card. I am using radeonfb.

I had a similar problem, and solved it by using the "wrong" (aty128fb) 
module which makes me happy. Booted working 5-6 times now, which is a 
few weeks since I run for long periods.

After bootup, the screen sometimes looks like it is melting.
I made a video to show you what is going on:

It does only happen sometimes. I could not find
a way to reproduce it.
If I start X after boot with a melting screen, X is also
melting:

But here comes the interresting part:
If I switch back into the console, the screen becomes
normal again and I can continue to work as usual.

I am suspecting some initialization routine bug.
It never happened when booting into OSX.

In X I use the "radeon" driver.

   Obscure bug of 2004: BASH BUFFER OVERFLOW - if bash is being run by a
normal user and is setuid root, with the "vi" line edit mode selected,
and the character set is "big5," an off-by-one errors occurs during
wildcard (glob) expansion.
