Another posible solution:
Get a 10ドル USB->Serial adaptor, and share the USB device into domU.
Those adaptors have some different timings compared to "real" serial ports, 
but if its just for AT Commands/GSM TextMessaging, you should be fine.
(Does sharing individual USB Devices work, even if they require a kernel 
module driver? Or do you have to hand over the entire PCI device of the USB 
HCI to domU?)
