Subject: Should I use bridge for this or just rely on the routing table?

I've got a ThinWire network connected to my NetBSD system since  ThinWire
interfaces are increasingly hard to find and don't support Fast Ethernet.
Since I just bought a new box which only has a 10BaseT connecter for 10/100
Ethernet, I decided to start upgrading so I bought an 8-port switch and a
10/100 LinkSys PCI NIC to go into NetBSD.  But some of the devices on the
ThinNet have to stay there so they'll have to stay on the old 10Base2 card.

Here's what I have now:

Cable Modem
    NetBSD system
      |    +-(ep0)----------ThinWire, local systems in
      |                  assigned subnet
      +-(wi0)----------Wireless (

Here's what I will have:

Cable Modem
    NetBSD system
    | |    +-(ep0)----------ThinWire, systems that have to
    | |                      stay on ThinWire, in
    | |                  assigned subnet
    | |
    | +-(wi0)----------Wireless ( subnet)
    +--(new Linksys card)--- Switch -- ( subnet)

So the question is, should I use the new bridge driver and
bridge ep0-wi0-and the LinkSys (whatever it is)?

Or should I just fiddle the routing a little more like I did
for wi0 and ep0.

(ipfilter is running, of course, but mostly on ex0 with some
less stringent rules about wi0.)
