On an almost-related note, at some point in the past, I had discussed on 
this list (with Sridhar?) the possibility of using a WS-X5410 9 port 
gigabit module with WS-G5483 1000baseT GBICs in a cisco catalyst  5000.  
Even though cisco documentation says that the copper GBICs will not 
work, they do work just fine.  CatOS sees all ports, and shows the ports 
with the copper GBICS as 1000baseT.

There are a couple of limitations in my setup, however.  Since the 
catalyst 5000 only has a 1.3Gbps backplane, performance between the FDDI 
and 10/100 ethernet portions of the network could be limited.  This is 
not a problem for me since we're talking about my home network with only 
a handful of hosts.  Due to an ASIC limitation, the WS-X5410 cannot use 
jumbo frames, which sucks.  Had i known that, i probably would have 
opted for getting a couple of the 3 port modules, and living with the 
backplane limitation between the two modules, or finding  a 5500 chassis 
to move everything to.
