pci_is_pcie checks for a PCI-E capability offset that was determined by calling pci_find_capability during the PCI bus walking. Based on your description above this should be functionally equivalent. If this is not safe, then the PCI bus walking code is most likely busted on EEH enabled PPC systems (and that is a BIG problem).
Are there PPC systems that support PCI-E cards? I looked for one earlier and did not find any. In particular, I wanted a machine to test the Realtek drivers for correct big-endian operation. I settled on a Powerbook G4 so that I could test the USB drivers.
