Ok. Something happened. How do I calculate that value? (I have 384 MB RAM).  

cbb0: <TI1410 PCI-CardBus Bridge> mem 0x10000000-0x10000fff irq 11 at device 9.0 on pci1
start (10000000) < sc->membase (80100000)
cardbus0: <CardBus bus> on cbb0
pccard0: <16-bit PCCard bus> on cbb0

cbb0: Unsupported card type detected

There is no card in the bus when this message appears. (And if I insert my Netgear MA-401 nothing happens.) 

Thank you
