soon attach directly to pcic rather than the kludge pci-pcic device we have now. In some ways, this is similar to the work PAO3 did to try to support cardbus bridges. In some ways different. This and future commits will be taking from the spirit of many of those changes. pcicvar.h is completely different from the pcicvar.h that appeared in PAO3, but similar in concept.
