The address you see is a raw physical I/O address, which is a concatenation
of the I/O window physical address for that PCI controller and the
PCI bus assigned address.

This is what we store in the resource values.

The pci_assign_resource() path must have some bug that causes the
resource values to be set incorrectly or similar.

Meelis, what is the value of pci_resource_start(pdev, PCI_ROM_RESOURCE)
before the pci_map_rom() call?
