That list probably needs updating again...

Yes, it will.  In VT mode, Xen and dom0 co-operate to simulate the rest of the 
devices of the PC platform - that code is in the current unstable tree.  For 
full performance, you'd probably still install versions of the Xen device 
drivers once the domain was up and running, however.

The code in the unstable tree can run an unmodified Linux install in a VT-mode 
virtual machine already.  Further work is required to get Windows booting, 
since (IIRC) it uses a load of 16 bit cruft which is not currently supported.  
I'm not sure that Windows support will be available for 3.0 but it will 
become available eventually.

Cheers,
Mark
