Ok, just in case it helps anyone.

I had a really ugly soft lockup on my desktop. It is running the Feisty release version. The install failed
while booting the live disk, as the xserver was unable to start. So I booted the live disk in Safe Graphics Mode
and everything worked fine using the standard xorg VESA display driver. Now that I've got a nice Radeon X1600
(RV530LE) PCIe card, I installed the fglrx out of the Feisty apt repository. Everything just standard. But it
totally wrecked the machine. Using the fglrx driver I got a soft lockup at starting arbitrary programms.
Sometimes even while loading the gnome session itself. To check if it had anything to do with compiz and
the nice wobbling windows (that couldn't even be activated) I removed compiz and used the standard
metacity window manager. Nothing changed. I still had lockups everytime I started an X session. So finally
I suspected the darn fglrx and removed it from the system, reenabling the vesa driver and - rataplan - no
lockups ever since:-) Yeehaw! Got my system back. So if anyone is experiencing this really annoying bug,
CHECK IF YOU GOT THE FGLRX INSTALLED AND ACTIVATED. IF SO, REMOVE IT AND TRY AGAIN. Anyhow I also
noticed it is related to some other drivers as well, but this time it was the fglrx for sure, so give it a try without
it.

good luck to all of you having a lockup on your machine

greetings sven

Output of lspci -v, lsmod, uname -a, cat /proc/cpuinfo; cat /etc/X11/xorg.conf attached in the text file

Note: The output of lsmod and xorg.conf are made without the fglrx driver. The way it would look like with
the fglrx driver loaded only differs in the vesa driver line in xorg.conf and one line of lsmod output.
