Done for Jeremy's 2.6.31.6 - initrd-2.6.31.6.img :-
init has been modified
modprobe -q drm debug=255
Image rebuilt :-
find . | cpio -o -c | gzip -9 > /boot/initrd-2.6.31.6.img
Xen Host reloaded .
Dmesg reports now :-

I guess this is some other problem then.. you might want to enable more
debugging options for drm to see what actually goes wrong.
Basicly you should extract the initrd image, and change the "modprobe drm"
line to say "modprobe drm debug=255" in the init script. And then
repack the initrd and use the modified initrd instead.
Does it work with "nomodeset" btw?
