The power off function didn't help. It looks like it's not going to be
possible to use these DVB-T cards in PCU passthrough mode. I didn't
want to turn my back on XenServer/XCP, partricularly now that
XenServer has gone open source, but the fact is that I can pass these
PCI cards through really easily in VMware's ESXi so that's where I'm

Perhaps when XenServer's PCI passthrough capabilities get better I'll
come back, but in the meantime XenServer/XCP are out for me :(
