You can't use two 3c503 cards; I NEVER did get that to work. 

A 3c503 and a WD8003 do work however.  But you have to edit the config files
and /etc/netd.cf yourself.  No big deal, but a small hassle.

There's a fix for the hanging streams.  I haven't run it long enough to be
sure it really fixes the problem, but it appears to so far.

Posted here 'cause I'm sure others have questions about this problem.  It's
been there since at least 2.0.2 (first one I used TCP/IP heavily with).
