Hrm... I don't support ppc32 on any G5 anymore, you should really
consider a 64 bits kernel. Note that there are some issues still with
the coe in -rc3, there is a patch in -mm fixing them. That may explain.
most of the errors below are actually spurrious ... the real error would
be if the message appeared twice in fact :) That's something I need to
fix.

Try current -mm and let me know.

Hrm, A more detailed report would be useful here. "I get flickering" is
close to the lowest you can get in that area :)
Things like: type of monitor, type of connector, dmesg output (with
radeonfb verbose debug config option enabled), x.org config file and
log, when does the flickering happen ? in console ? in X ? in both ?
what precisely do you call flickering, etc.. etc..
X.org 6.8.2 lacks a number about a dozen patches I made to fix various
issues on ppc, you may want to try them, they are in X.org CVS HEAD and
patches against 6.8.2 are at:
http://gate.crashing.org/~benh/xorg/
The "series" file will tell you in what order to apply them. Note that I
think some distros like Ubuntu already picked up a number of these.
