This is a recipe for disaster.  The nVidia kernel driver has a binary 
layer that it not Xen-ready.  It's very likely that it's going to be 
doing something it's not supposed to do in Xen.
You're out of luck until nVidia releases a Xen driver.  You can also use 
the Open Source driver (or even just Vesa).
This is why binary modules are so evil...
