I guess this is as any good place to also point out that there is an
alternative. You can use the nouveau driver (but it does not have yet 3D
support), which works with the Xen PVOPS kernel. Better yet, Kernel
Mode Setting works as well!

For details: http://wiki.xensource.com/xenwiki/XenPVOPSDRM

and if you want to try out the 2.6.34 nouveau driver on a Xen PVOPS
kernel, get it from
git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git branch devel/next.drm
