Sounds like it's related to the newer DRM.

Typical symptoms of a graphics chip lockup.

FWIW, I can run all screensavers from the kscreensaver package from sid
on my TiBook with a Mobility Radeon 9000 running a 2.6 kernel with my
DRI snapshot packages described in
http://dri.sourceforge.net/snapshots/README.Debian without problems. The
XFree86 4.3 packages in experimental may also work better.

These are indeed unrelated and harmless.
