I think you can pass individual IO ports and interrupt through to a PV
guest without necessarily passing through a PCI device.
I'm afraid I don't actually know the exact runes to cause xend or xl or
whatever to do this though -- I think perhaps for xend lines like:
ioport=03f8-03f9
irq=3
(or whatever the com port uses) in your config file might do the trick.

I'd expect that to work alright.
