Yes, that should be fine. Just an FYI - when you introduce the over-ride, I believe that it should be __init and not __devinit as the previous tile version of 'pcibios_setup()' was.

Looking at the tree I only see three of the architectures currently using/implementing "pci=off" (four with the 'tile' addition). Perhaps there is a way to avoid such but it seems like adding this to the core would require introducing the global variable 'pci_probe' which seems like unnecessary pollution?
