The XP port was written for Xen 1.0, which was quite different in a number of 
respects.

I've not seen the code, but I imagine there is driver code that could be 
reused.  Exactly how useful it'd be is not clear: the Xen driver interfaces 
have changed a bit since then, although there would still be some 
commonality.

Work is underway to make the paravirtualised device drivers run under 
otherwise fully-virtualised Linux.  Once the implementation approach has been 
agreed upon and completed, somebody should (in principle) be able to apply 
the same approach to Windows.  This could usefully employ the drivers from 
the original port, but there's still going to be a load of work implementing 
stuff like a XenStore interface, grant tables support, etc.

Cheers,
Mark
