I'd like to try the patch, though I didn't see a locked up X either
(probably atyfb64 isn't affected?), but the CPU usage of xmms is also
outrageously high on my Lombard, and there seem to be occasional drop-outs
in the sound (as if the processor can't even always keep up with decoding
the mp3s).
My problem is that my kernel compiled from the rsynced 2.2.17pre10-ben1
sources won't even boot beyond the first stages, to starting up the swapper
- xmon reports

vector: 300 at pc=c00f7854, msr=9032, cp=cp03fb820 [c03fb770]
dar=c8001304, dsisr=42000000
current=c03fa000, pid=1, comm=swapper

without the patch as well as with it. The precompiled 2.2.17pre9-ben1 runs
without significant problems (other than the sound one).

What's more strange, the crashes even seem to affect OF, especially when
I tried to boot with yaboot. Afterwards, I noticed the Mac didn't find
the boot volume and searched for a while til it found my MacOS system
folder. I discovered that all OF boot vars had been set back to defaults,
maybe PRAM had been zapped completely, because also the function keys had been
set back to Brightness/Volume keys etc.
This happened several times after a crash, does anyone know how to avoid
this?

Greetings,
							Derek
