May be you should use two embedded hardware (to acomplish yours
BSDRouter) like this:

or like this:

The second one is more expensive than the firts one.

Attaching one poweful mini-pci Atheros wireless card on each hardware
embedded you might could get large distance.

you ought to use one mini-pci wireless card like this:

http://www.netgate.com/product_info.php?cPath=26_34&products_id=694

it's a very expensive wireless card but it's  very powerful card too,
it work with 1watt of power when work in IEEE802.11g/b modes also you
need to use two good directional antennas may be like this:

http://www.netgate.com/product_info.php?products_id=395

I had used the embedded hardware http://www.pcengines.ch/alix2d0.htm
with NanoBSD and I got good results but i never need getting large
distances like you.
