I'd prefer these things to retain a positive-logic construct, so:
if (machine_is_cats()) {
bus_register_notifier(&pci_bus_type, &footbridge_pci_dma_nb);
pci_common_init(&cats_pci);
}
It's the same number of lines.
Otherwise, I think it's fine. I'll try to find some spare time to give
it a go on a Netwinder.
