It seems like it should work to add another ethernet NIC to the bridge 
if you want all the clients to appear on the same net - with some 
overhead for propagating broadcasts between segments.  That should be 
easy enough to try.  If it doesn't work or you don't like it, you should 
also be able to configure two separate client subnets if you adjust the 
dhcpd.conf file, iptables and any other permission-related settings.

You may have to change your cable from a crossover between switches to a 
non-crossover to the server NIC - but I think gig connections are always 
supposed to autodetect.
