     The bridge driver creates a logical link between two or more IEEE
     networks that use the same (or ``similar enough'') framing format. 
     example, it is possible to bridge Ethernet and 802.11 networks
     but it is not possible to bridge Ethernet and Token Ring together.
     The bridge driver currently supports only Ethernet and
     (e.g. 802.11) network devices, with exactly the same interface MTU
     as the bridge device.

If you can live with 10BaseT on the Ethernet side the Cabletron ESX-1320
is a neat 12 port 10BaseT switch with an optional FDDI uplink module
(BRIM-F6). I have two of them and they "Just Work" (C) (R) (TM).
