Simply put, your video hw/driver apparently doesn't support compositing. kwin is *supposed* fail more gracefully than this, however.
kde-4.1.1 has a few fixes that may help here.
In the meantime, you can manually disable compositing (desktop effects), but editing ~/.kde/share/config/kwinrc, and change
AFAIK, the test to check if compositing is actually working is not in 4.1.x, only 4.2. OpenSUSE has a backport we could snatch though. Note that 4.2 and OpenSUSE's backport also enable compositing by default (because it has this self-test and automatic fallback now), this is something I don't think is a good idea in an F9 update at this point.
Closing this as NOTABUG since its a hardware issue.
