: In the dmesg output:
: cbb0: <TI1450 PCI-CardBus Bridge> mem 0x50000000-0x50000fff irq 11 at device 2.0 on pci0
: cbb0: Reserved 0x1000 bytes for rid 0x10 type 3 at 0x50000000
: cardbus0: <CardBus bus> on cbb0
: 
: If I understand this correctly it should use the PIC-Cardbus bridge.
: Is there anythng you want me to try?
