    Let me guess: a Lucent Orinico PCI adapter, right? It should work with
    linux-2.4.6, I submitted a patch for 2.4.6-pre8 (or so) and it is
    included in linux-2.4.6. I currently have it working on two non-SMP
    systems (ALi 1541 and Intel 440FX chipsets).

    Make sure that the Cardbus driver is not a module. IOW: your kernel
    configuration should have these lines:

    # PCMCIA/CardBus support
    # CONFIG_I82365 is not set
    # CONFIG_TCIC is not set
