pci=off is used for a different reason. The BIOS firmware boots the controller
at 0x180 even though its cardbus or pcmcia. Our cardbus layer loads and 
deconfigures it at which point the s**t hits the fan (actually the result is
more like a sewage tank going through a jet engine intake)

To kill the pci=off we need a cardbus driver for the chip, which old IDE
couldn't do (because we can't unload old-IDE PCI drivers)
