Xen (the unstable.bk version) has the capability to expose individual
ISA devices to guests. However, the control tools haven't caught up with
this yet.

You can do it in a hacky way for the moment though, by giving the domU
full IO privilege. If you do this, you'll have to be careful to ensure
that only one domain has a driver for the parallel port, otherwise bad
things will happen if they both try to access it.
