For a Linux domU right now, your best bet is to use X protocol over the 
virtual network (but this will be slow).  For Windows, it's not possible now 
I'm afraid.

Further in the future:
* Jacob Gorm Hansen has written a paravirtualised 3d driver called "blink" 
that may allow this (nb. currently for Linux / Unix guests)
* You might be able to give Linux guests access to a separate PCI graphics 
card using the PCI assignment stuff

If you want Windows games, I guess you could use Wine / Cedega .... ?  Of 
course if you did that, you might as well run in dom0 or on native Linux!

Further developments include efforts by some companies to develop a 
virtualisation-aware 3d graphics card that'll support multiple virtual 
machines, and the IOMMU work mentioned.  It'd also be possible to emulate a 
full 3d card to the Windows guest, but it's not clear that'd be worth the 
effort.

Sorry there's not a better answer right now :-/

HTH,
Mark
