11.10 unable to wake up from sleep with Radeon Mobility chipset

[Yuri]

I have a fresh 11.10-desktop i386 installation from CD + updates from internet on IBM ThinkPad R51 laptop.

OS works, but after I close the laptop cover and it falls asleep, and I open the cover, it comes back with the black screen.
I can see that OS itself did wake up, I can type password to come back into the workspace (I can see this from the cursor changes). But screen itself stays completely black.

Killing X (Xorg) process from the black terminal doesn't help. X comes back with the black screen again.
