I have just got one of the latest 12" iBooks, and have installed 2004.1 on it. Unfortunately I can't get X working, nor can I get a framebuffer console using radeonfb (ofonly works fine though). If I use video=radeon or video=radeonfb, I see the framebuffer for maybe half a second and then the display dims. I've seen previous posts about this but have not been able to find any info which would fix it on this iBook.

Has anyone seen any info on this? I'm using development-sources-2.6.6.

Currently typing this in lynx ;)

Did you apply the 7447a patch??

Check out this thread if you haven't already:

I was having the same problems with my 12" G4 iBook install as well, but applying the patch and recompiling the kernel helped. You'll probably still get some flickering during the init process, but it will stop once X boots up.

BTW, I'm currently using ppc-development-sources-2.6.5_rc2-r1

Sensational! I'm now typing this in Firefox :)

Thanks sienarot! I had actually seen that thread, but I presumed that the needed patch would be in-kernel by now (I'm using 2.6.6). It seems that the stuff for the CPU is in 2.6.6, but the stuff for the radeon isn't.

Glad I was able to help!

Hopefully you didn't spend a week getting X going as I did!

Tieing up loose ends for anyone looking at this thread in the future: the patch referred to here for fixing the radeon flicker is in-tree as of kernel 2.6.7.
