I've also attempted to activate DRM for Radeon in kernel 2.6.31.1 ( the most recent) under Xen 3.4.1 & Libvirt 0.7.1-8 on top of F11 and lost GDM login at all.
Switching /etc/inittab to initdefault 3 also doesn't allow to login in text mode.
Disabling DRM ( rescue mode kernel rebuild) brings things back to usual behaviour. X-Server just starts , no matter of DRM status ( vs Ubuntu 9.04 Server)

So you're saying it works? I didn't see anything bad in the dmesg output.

If it is working, what does /proc/mtrr say?

Thanks,
