NetBSD can also be used as the privileged domain (dom0) running under 
Xen 2.0 (though not yet under Xen 3.0), so the NetBSD sources are still 
a useful starting point for you if you're planning to pursue porting 
OpenBSD to Xen to run as a privileged domain.
However, I think it's probably more useful to start by porting OpenBSD 
as a guest domain -- you're going to want to run all your services in 
guest domains anyway to take advantage of the security-through-isolation 
that Xen provides.  In my own setups, the only critical thing that dom0 
does is keeping the clock accurate for the guest domains, though it 
might make sense to also provide, e.g. DNS or DHCP services in dom0 as well.
