Try telling SRM:

	>>> set pci_device_override -1

and it'll stop complaining. But you need to be sure that the drivers
for the card you put in the 64-bit slot doesn't violate some of the
guidelines necessary for working in an early PYXIS-based machine...

I don't understand this; are you saying that when you move the cards
into the 32-bit slots behind the bridge, the Linux kernel doesn't
initialize them correctly?

Yes, well, that does slow them both down, passing through the bridge
and all. Try the above incantation and SRM ought to allow them both
in the 64-bit slots, and you should be alright with them there.
