Thread-topic: [Xen-devel] [PATCH(es)] graphics passthrough with VT-d
Thanks for the steer Alan, it would be ok for limited support and testing but I 
don't think it would be supportable to maintain Xen specific board 
initialisation code especially when the DomU is HVM running Windows OS .. you 
would want to use the Nvidia shipped drivers..

Or to do your own board initialisation code for a cheap board - there is
sufficient code in the Linux nvidia fb driver and/or the Nouveau codebase
for that for a fair number of boards.
