Hi Dave, Rafael,

I can successfully suspend/resume my HP Envy, but upon resume,
the screen is corrupted.

I used the gnome screenshot utility to capture this:

	http://chizang.net/alex/tmp/radeon-4830-corruption.png

But that screenshot leads you to believe the corruption was
100%, when in reality, the text in my xterms was at least
readable, but ugly.

Kernel is latest upstream pulled today. Userspace is Ubuntu Karmic.

Some info inline; xorg.log and pm-suspend.log attached.

Thanks,
/ac
