Also, what if you reboot the domU - does the fact that you can't do an FLR on the card mean that there will be unpredictable results the 2nd time domU tries to initialise it?
Yes. FLR is required by pci passthrough. your NIC only can be co-assigned (#1). #2 is just a temporary workaround for your try.

Is there a way of finding out from a running system whether a PCI card supports Feature Level Reset?
