I've got exactly the same problem. The only difference is that I use random screen savers and when the display is frozen I see the screen saver image frozen and not the desktop wallpapaer as Bernhard does.
I'll attach same files you asked Bernhard for.
My uname -a output is:
Linux U-PT250 2.6.24-24-generic #1 SMP Thu Feb 19 08:00:07 UTC 2009 i686 GNU/Linux
