4.1-rc7: Xorg broken after resume on thinkpad T40p, radeon problem?

[Pavel Machek <pavel@ucw.cz>]

Hi!

Video is broken on thinkpad T40p after resume from suspend. (In X
only, text console still works.)

Maybe this is related?

Hibernation works well here, including X. (Which has small glitch with
mouse cursor being corrupted until it is changed by application).

Any ideas?
