Hi Dave,

This patch series contains the gpu sharing layer for kernel that
I've mentioned before. It should apply against Linus's git tree.
I gave the patches a go on my PowerBook. I had to make a few changes
to get it to compile. Works fine so far: I switched between VTs and X
with an accelerated GLX client active a few times, no problems.
When I did a sleep/resume cycle it wedged on resume, but I expect this
is due to my hacking up radeonfb_early_resume(), as seen in the last
hunk below, which was just aimed at just getting it to compile.
