We also use OpenBIOS for PPC and Sparcs. A compatible boot device for
those would be OpenFirmware tree name. I think your names should then
become:
/pci/isa/address@hidden/address@hidden
/pci/isa/address@hidden/address@hidden
/pci/address@hidden/1,0
/pci/address@hidden/1,1
/pci/address@hidden
/pci/address@hidden

The PCI addressing scheme in OF was a bit twisty, I just invented
integers in place of those.

Anyway, I don't think we should invent yet another device path naming system.
