Surprisingly I have a different cardbus slot to Kurt:

cbb0 at pci1 dev 3 function 0: Ricoh 5C476 PCI-CardBus Bridge (rev. 0xac)
cbb1 at pci1 dev 3 function 1: Ricoh 5C476 PCI-CardBus Bridge (rev. 0xac)

Solved by adding

options     PCI_ADDR_FIXUP

(before only PCI_BUS_FIXUP was needed...)

Cheers,
