Yeah, I misread the spec when I wrote: this one is specific for
PCI/PCI-X, and not PCIe. That probably explain why this was not
implemented in practice yet.
I'll rename it.
Still, it is good to test it, even not being implemented, as it
helps to check how Linux reacts to a GUID it doesn't know about
it.
