        I've bought a PCI <--> PCMCIA/Cardbus adapter card

          ENE Technology CB1410 CardBus Controller (CardBus bridge, revision 

        to use wlan cards in my desktop pc (w/ an asus m3a78-t

        The PCI card seems to be detect fine by the kernel (dmesg

          ppb2 at pci0 dev 20 function 4: ATI Technologies SB600 PCI to PCI 
Bridge (rev. 0x00)
          pci3 at ppb2 bus 3

          cardbus0 at cardslot0: bus 4
          pcmcia0 at cardslot0

        , but no inserted pcmcia or cardbus card is detected!

        According to cbb(4)'s BUGS section I tried to decrease system
        memory from 4 GB down to 512 MB, and also 'options
        RBUS_MIN_START="0x20000000"', but with no success.
        Plugging/unplugging pcmcia/cardbus cards show no kernel

        For completeness here the adapter card's pcictl dump:
