I tried this, to no avail.  I've checked that the pciback driver is
taking control of the device now:

dmesg | grep pciback
pciback: seizing PCI device 0000:06:00.0

However, looking at my xend.log, I can't see anything about the pci
device.  Even when it spits out the config at me, I don't see anything
related to pci...
