That's okay with me. We might use a PCIe switch to split an x16 lane
(used normally for PEG) into two x8 lanes (used for our own nefarious
purposes including MSI for sure). These should all pass
PCIe-deviceness through the switch to a root complex (in all the
targets we've looked at using), however, and so should be unaffected
by your new PCIe detection, regardless of blacklisting a PCI or PCI-X
to PCIe bridge.
