Hum... Both cards are behind the PCI<->PCI bridges, and so they should
both have io addresses in the range fe001000 -> fe001fff

The fact that they are at fe000000 seems to indicate that the io base
address is 0 (and so was apparently _not_ assigned at all). Could you
break into OF, dev to those devices, and send me the output of
.properties ? (I need the content of the "reg" and "assigned addresses"
properties). I want to see what OF did with the cards exactly.
