Actually the PCI device hiding does now work on Xen 3.0 so you could assign a 
graphics card to a domU.  I think people may have done this successfully 
although I'm not sure how functional they managed to make the resulting 
system; X.org used to get a little unhappy and confused when run in a domU 
even with access to the graphics card.  Maybe this is better now.

Giving PCI devices to HVM isn't possible (at least not until suitable IOMMU 
support is available - both a hardware and software problem).

I wouldn't expect compiz / beryl to work well if forwarded from another 
machine (or even from a domU), although I'd be interested to discover if you 
*can*.

Or SSH to the guest and use X protocol forwarding - works very well and 
integrates well with your dom0 desktop.  Or use NX (NoMachine X) to forward a 
desktop with sound, storage and print services (if you can get it to work!).

Cheers,
Mark
