Mike Smith and I have been talking about putting this into
pci_cfgregread rather than making it a special case in the MD code
that dev/pci is supposed to be. The machine specific ifdefs in
dev/pci/pci.c are to be avoided.
We do this re-mapping right now for tha APIC case on i386, but should
also do it for other values in the non-apic case.
