Ooh, that sounds promising! Theoretically, if PCI-passthrough could be
enabled and disabled on-the-fly... Does PCI-express still has enough
backward-compatibility to direct PCI-passthrough to it?

... though anyway the patched driver is Linux only. So it will help to
run Linux as host, and even, probably, to run Linux as guest, but to
run Windows utilizing all video features, the only way is to write
something generic - and the efforts of manufacturer driver developers
won't much help here (as it helps with dom0), cause the solution
should be at XEN level - right?

Well, with Linux-as-guest it should be possible - but I think neither
of those network sound daemons can help with Windows-as-guest, right?

Well, but ntldr won't boot from it, I guess. So well, let's stick to
disk images.
