Yes, I looked to .old, when referring to Xorg.0.log.

So, I've now the acceleration. The main problem was radeon.agpmode,
setting it to -1 (and removing all files in xorg.conf.d related to
radeon) fixes all issue (also the freeze on glxgears). Now I have
~1500 FPS, and I'm fine with it (before I got 100 FPS).

I get the acceleration also with a non-KMS capable kernel, so I think
we got the point. I will add the option to modprobe.conf for archPPC.

I tried a program which use a lot opengl, the only thing I see is
ERROR: GL error 1282
ERROR: Ignoring 1 openGL errors

but the topic-error is fixed.

Thank you.
