at the point where we cross from 5V to 3.3V is not the normal case.
The added complication is that we don't know that the 5V slots are
always bus 2, because a card containing a PCI-PCI bridge may be
plugged into a 3.3V slot, and this changes the bus numbering.
Also, the Cayman has an intermediate PCI bus that goes a custom
expansion board header (and to the secondary bridge). This bus has
never been used in practice.
