After installation of xserver-xorg-video-intel package, the problem disappeared on my thinkpad. So indeed there's probably something wrong with the default intel video driver. Maybe this will help the other guys with intel video cards - can you check if that solves the problem for you as well, pzi? Still, I don't know why there is also a problem with radeon x3000... :/
