Hi! all,
 I found that wireless usb adapter BUFFALO WLI-U2-KG54-AI is supported
by ral(4).Does it support by netbsd3.1/macppc?
There  is no associated ral interface showing up in My netbsd3.1/macppc.
When i add these(ral*) to new kernel,config mynewkernel,
i got error:unknown device 'ral'.

    ral* at cardbus?
    ral* at pci?
    ral* at uhub? port ?

Thanks,
 gnosy
