GFX Speed is fine now after resume on my Thinkpad R61.
Brightness control is still not working though.
Not havoing to restart X after resume is more important though.
So thanks alot for that fix.
The lack of brightness control can be workarounded by switching
to a text console, adjust it there and then switch back to X (vt7).
Of course that workaround doesn't mean it the issue can be ignored.
