Actally I think the missing word, in both cases, is register,
unless I am misreading some part of the manual page and
what a struct pci_io points at. I guess if the pi_reg is null
then this would be device. Either way there is defanity a
missing word.

RAM memory == Random Access Memory Memory
PCI == Peripheral Component Interconnect
PCI {Register, Device, Bus} all make valid sense,
PCI alone does not.
