It was the same system with the Radeon card detached. The i915kms.ko was
loaded via the rc.conf and the xf86-video-intel port was installed and
loaded with the xorg.conf file. Tomorrow i can upload the Xorg.0.log files
if they are needed.

No coredump because i disabled it with kern.coredump=0 but i can change
this and look if a dump will be created. Tomorrow...

Which Ubuntu version should i try? How can i create such a chroot. Is it
possible to install an Ubuntu on a separate disk, tar it up and unpack it
to /compat/linux.
