OK.  I looked at the datasheet for the Vr4171, which is the only
datasheet for the companion bridge sets that I have in paper form.
The 4171 provides what looks to be a Vadem 469 compatible interface
for 3.3V.

However, looking at the "data brief" two pager that I have from nec,
it appears that the 4172 doesn't have the pccard stuff built into it.
Which is a shame too since it does a lot of cool things, none of which
are exposed on my R430: usb host controller, Parallel port interface,
a second serial port (although that may be the cellphone connector)
and a PS/2 keyboard/mouse interface.

So I guess I'm going to have to take my R430 apart to see what the
actual chip that's used inside is so I can find out how to program
it.

I wouldn't be surprised to find the vadem chip, nor would I be
surprised to find one of the Ricoh chips.  NEC has used both in the
past.
