After putting the Radeon driver provided with x.org to use in my
Thinkpad T41, after wakeup from suspend to RAM, occasionally the screen
becomes garbled:

Note: This is a screenshot (done with ImageMagick's import)!
Consequently the content of the X framebuffer is garbled which I find
quite weird, especially when I consider that ...
... some of those vertical colored lines do slightly flicker.
... the problem usually goes away after another suspend to RAM cycle
(fortunately!).
Also: Yesterday, my mouse cursor suddenly became garbled, out of the
blue. In this case, a suspend to RAM cycle also fixed the problem.
Did anyone else experience this problem? Assuming that it is not due to
faulty hardware, what software should I try updating: The kernel, X.org,
something else?
Some info about my system:
* Model: 2373-3KG
* Graphics: Radeon 9000, internal XGA TFT (i.e. no external display
attached when the problem occurred)
* Processor/chipset: Centrino 1.6 GHz
* Linux installation:
