The lspci I have received for a k8s-mx exhibit a 5513 whose PCI ID is
already correctly set. If the ID masking and register remapping is not
really relevant on a 180, the code below could be enough. If it is wrong,
it may be better to check the availability of a good backup system before
using it.

Some features documentation suggest that the 760 and the 755 should
mostly go along with the same southbridge.
