Does the PCI specification allow for programming the
PCI to PCI bridge primary bus number register to a
value less than what is programmed in the secondary
and subordinate bus number registers of a particular
PCI to PCI bridge?  Assuming this is possible, can you
foresee any operating system problems I might
encounter with this configuration?
