Even before the changes Alan mentioned we had a bunch of machines like the
SWARM which had PCI but it's PIO IDE adapter wasn't living on the PCI bus.
So disabling PCI on that machine would disable IDE also.  Other machines
had IDE on PCMCIA with the PCMCIA bridge not hanging off an (E)ISA or PCI
bridge.  Basically I could have changed that if statement into an
increasingly obscure and braindamagedly complex if statement.
