Allow forcing on all GPU clocks

2.6.38 should be fine for this test. But at some point it'll probably be useful
for you to be able to try kernel patches. Once you've built a kernel, building
the radeon module with a patch shouldn't take long.

E.g., you guys could try this patch, and booting with radeon.dynclks=0, which
should force on all GPU clocks. Does that increase stability with agpmode=1 or
agpmode=-1?


> BTW, would you mind sharing your .config?

My .config still takes 1-2 hours to build on this 1.6 GHz PowerBook. If that
could help you, please ask for it on the debian-powerpc list.
