Comment 79 for bug 140051

Jordan of AMD pointed out that, according to your Xorg.log, AmdProbe is calling xf86MatchDevice and that is failing. The only reasons he can think of this ever happening is whenever the BIOS has no VSA layer (or equivalent feature) and no /dev/cpu/0/msr.

Billy, as a test, can you perform the following steps:

1) sudo echo "msr" >> /etc/initramfs-tools/modules
2) sudo dpkg-reconfigure linux-image-2.6.24-16-generic
3) reboot
4) go into a console with CTRL+ALT+F1
5) sudo lsmod | grep msr

...and tell us if that improved anything?
