Markus, can you send me a copy of your vbios? as root:
cd /sys/bus/pci/devices/<pci bus id of video card>
echo 1 > rom
cat rom ? /tmp/vbio.rom
echo 0 > rom

Also, when you say "on reboot" do you mean the card comes up ok
initially with the new kernel and then fails after a reboot, or fails
directly after booting the new kernel?  Also, is there an oops or
anything like that in dmesg?

Thanks,

Alex
