If the PCI host bridge really only supports PCI bus 0 and 1 then you
may be out of luck, but I would try booting with "pci=assign-busses",
and also try "setpci -s 00:0d.0 a1.B=5" to increase the subordinate
bus limit for the PCI bridge for bus 1.

No way. The Cardbus card will appear as device 0 on the subordinate
bus, and you've already got a device 0 on PCI bus 1.
