Ok, I removed nouveau_dri.so. Unfortunately, it didn't help. I know that
probability theory can be tricky. :) But the system lock occurred three times
within a period of 24 hours, whereas the past frequency was approximately once
a week. One could conclude that removing nouveau_dri.so made it worse.

Here is a short log of uptimes that were affected by this bug.
0 days, 01:49:19  | Linux 3.0.4-gentoo        Thu Sep 29 09:59:24 2011

6 days, 14:00:20  | Linux 3.0.1-gentoo        Mon Aug 15 19:39:40 2011

Thus, I moved nouveau_dri.so to /usr/lib/mesa again.

This bug is not that bad since I am still be able to work. But I am a little
bit concerned about data loss after a crash.

> Now that sounds unusual, any chance of a serial console?

No, unfortunately not. I work abroad at the moment and I just have this laptop
without additional equipment. I might check it, when I'll be back home in
January, though. ;)

Is there anything else I can do?
I tried to save Xorg.log after a crash. I am not 100% sure if the log file is
complete, but I attached it nevertheless. I can't see anything unusual.

No problem. I have no experience in writing drivers. I guess, I am of little
help here. But the drivers are very impressive. Thanks anyway.
