The BAR values in PCI config space may be the same, but the BAR values in
struct pci_dev can be made different by the machine-specific fixup code.

This would work as long as no one reads the BAR directly. I know no-one
should do it, but I've seen some time ago (can't remember where) some
drivers reading BARs directly. Also, I don't know for the X server.

If drivers use the BARs directly, they're broken and won't work on other archs
like SPARC64 neither.

X should use /proc/bus/pci, which relies on struct pci_dev as well.
