Re: an driver with cisco aironet mini-pci 350

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.
