Basically, it looks like the GPU locks up. Does
Option "RenderAccel" "off"
in xorg.conf work around the problem?
You could try enabling KMS, but you might run into other issues with
that which Gabriel reported on the linuxppc-dev list. It might work
better with newer kernel/X/driver from testing/sid/experimental, but
don't expect any miracles.

You could just disable the DRI with
Option "DRI" "off"
in xorg.conf. :)
