We use Digi Serial-over-IP devices to pass through serial ports to domUs. We've had success with the Digi One SP, PortServer TS, and Passport devices. I currently use the Passport 48 for IP access to all of my serial consoles (Ethernet switches, RAID arrays, FC switches, etc.) as well as to pass through a modem to my HylaFAX server, which is in a Xen domU.

Well, I understand that it is a complex task, but maybe there could be a
list of "migrable PCI devices" that wouldn't give problems to Xen.. And
of course it would work only with ad-hoc configured machines.. I wasn't
getting into the details, I was just asking :)

A serial port.
