Ok, I looke at some code.

Lots of pcmcia cards have supsicious or missing numeric vendor and/or
product codes. Our pcmcia driver's match routine (if no chipset-specific 
one is used) as well as the if_ne_pcmcia.c match routine don't use 
vendor/product, but use the strings in the CIS. They're not very
specific here - somebody wanted to make sure never to be found by a
revengeful user I guess, or didn't want to do the letwork of replacing
the generic info in the chip's prom by card-specific info - but we an try

hehe. The reason is, that as far as I can tell, cnet.device doesn't do
any check on anything card-specific. If a card function type is provided
as network card, it believes it. If no card function type is provided,
it believes it is a network card, too.

If a different function type is provided, it rejects it (fortunately).

But if it is a network card with a different chipset, it will be very
confused. Try to put a 3c589 in oneday. Or better- don't try.

I came up with this quick one-file patch. To go officially in, we'd
put definitions into pcmciadevs, recompile the derived files, and use
the symbols in the driver, but for a test it will work fine. Go to the
top of your source tree, and pipe this e-mail into

patch -p0

or add the three line marked with +, without the plusses, after line 
183 in netbsd-current; then recompile the kernel.
