Apologies for the delay getting this out.

Some quick notes and the associated files for doing this can be found at
<http://pigeon.shipops.orst.edu/swap/bridge/>
Obviously the notes are in the file:
  2006-01-30.notes
The directories:
  tecumsa - the new config that does bridging
  test1   - the original config

There are minor changes to 4 files.  The one Harmon is probably most
interested in is 
  /etc/network/firewall-nat
which contains the masquerading rules to do the routing.
