Hi,
server crashes immediatly after start,
in advance to older drivers I'm able to switch back to vt.
At last versions I need to login from remote and reboot
computer.

It seems (see http://www.drillich.com/xorg/dmesg.log.gz)
that X tries to use a NULL Pointer.

any ideas to get closer to the bug
greetings thomas

        http://www.drillich.com/xorg/mmio-trace-fglrx-ati-rs480-amd64x2.bz2

need to switch back to kernel 2.6.22.6. 
In kernel 2.6.23 they did some garbage collection, removed depricated, and 
fglrx depends on that ;-)
