Mention of The Xen-Kernel:

Just a thought here. I never used the proprietary nvidia driver with the
xen kernel on any install of it I've done. But I beg to know why would
you even want to run that when you running Xen? If your running Xen then
your not after video acceleration correct? You after I/O and Memory

It's not a problem if you two want to validate a driver install of this
weird nature. I can do this. I have the extra machine for testing
purposes.  The only type of people that would maybe use this combination
would be strictly Developers.  I can see someone now, I have a Dell
Poweredge 1950 with a on board nvidia card and it runs the Xen
Hypervisor!!! Only connection to it is a Serial Console!
