Some more testing, this time with 'extremetuxracer' (3D game from Ubuntu sources).

This game works fine on my desktop machine (Radeon 9600 XT) with the open radon driver.
On the Thinkpad the game appears to freezes after 2-5 seconds. The music continues, though.

The backtrace is similar to the last one from the 3D screensaver (attached).
I tried to kill the game remotely which only worked via 'kill -9'
The screen stays the same but the music stops, so obviously it's not the game that froze in the first place but X.

Then I tried to restart X via:
$ sudo /etc/init.d/gdm restart
 * Stopping GNOME Display Manager... [ OK ]
 * Starting GNOME Display Manager... [ OK ]

Although it looks good in the remote shell, the screen stays the same and there's nothing I can do.
Finally 'sudo shutdown -h now' did work.
