-	   from the 3 3.3V slots.  Thus, we have to detect whether the card's
-	   interrupts go via the 5V or 3.3V path, i.e. the 'bridge swizzling'
-	   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.
-
-	   The 1ary onboard PCI-PCI bridge is device 3 on bus 0
-	   The 2ary onboard PCI-PCI bridge is device 0 on the 2ary bus of
-	   the 1ary bridge.
