It would be tricky. Even if we did support it, if the domU is connected 
to a network interface, or you use the balloon driver, then that will 
cause memory to start getting fragmented. But maybe it would be good 
enough -- this fragmenting problem will also occur in domain0 over 
time.
I think you'll have to stick to dom0 for now and hope someone on the 
ivtv list has some spare cycles to help you out.
