Since the latest Linux from Cisco has code to drive this card it shouldn't
be to hard to add support assuming they added the PCI attachment in
a reasonable way. It's now very difficult to get programing information
directly from Cisco :-( I have a mini-PCI to PCI adapter so I can
plug it into a couple of test systems including a Soekris box.
I have an older PCI version here. Hopefully we just have to update
the attachment and it should just work. Can you dump the the PCI registers
0x10 & 0x14 via pciconf -l. We can probably just skip over the indirection
of the PLX chip and go straight into attaching the Aironet driver to the
rid. You can try this guess at a patch for kicks.
