Do you aim for a Dom0, a DomU or both?
In any case, you'll have to rewrite things that aren't fully virtualized 
by Xen. This mainly includes memory management and interrupt handling.
For Dom0, you should be able to use the same drivers without 
modification (not sure though, don't have much experience with Dom0) but 
you'll need to write the frontend/backend drivers for virtual devices.
For DomU, you'll have to write drivers for virtual console, virtual disk 
and virtual NIC.
