will do for me.  The bigger requirement is that it works well with FreeBSD
8.2 and eventually 9.0.  If you had your pick of any (reasonably priced)
card that had two external ports and would work in my configuration, which
would it be?

I don't know what's out there having chosen only one such card for home
use.  So you'll need to do your own research.  Start with looking at any
card with the right chip and then look for evidence that people have used
said card with FreeBSD.

You should contact the driver maintainer and see if they're available &
inclined to take up your offer of hardware availability.

You may also have access to some talented young students who might be
interested in driver programming who could help.

As a production user of FreeBSD it's always great if you can find a way to
contribute back to the project in areas that help you too.
