And how are we supposed to get any MSI-X interrupts in this configuration?

Our fallback code for when nothing was matched in IORT (i.e. directly using PCIe RID with no offset) did not result in working interrupts.

IIRC legacy interrupts didn't work either, but maybe you should retest them (disabling MSI, MSI-X).
