If your Windows supports remote desktops (home Windows generally doesn't but 
the more expensive versions do) then you may find that you can get better 
graphics performance by connecting to it over the network using rdesktop.

You can also do rootless / seamless Windows virtualisation using remote 
desktop (see https://help.ubuntu.com/community/SeamlessVirtualization, 
http://www.cendio.com/seamlessrdp/).

Improving the performance of the actual framebuffer device in Xen would 
require some performance optimisations which I'm not well placed to explain.  
If you actually want to hack on the code, then you could try asking for hints 
on the xen-devel list.

Cheers,
Mark
