Mathematica 6 over ssh tunnel

I've been using Mathematica 5.2 with a remote kernel (OS X both for
the frontend and the remote kernel).  To get around a firewall, I've
used, essentially, the method described at the bottom of this page:

http://www.mathematica-users.org/webMathematica/wiki/wiki.jsp?pageName=FAQ_Remote_Kernels

This works well for Mathematica 5.2.  I recently upgraded to
Mathematica 6, however, and now everything works fine except graphics,
which come out with only a line reading "-Graphics-" and no actual
graphics output.  Has anybody else experienced this?  Is there a way
around it?

It appears that Graphics work if you connect with the firewall off
(and therefore, no need for the ssh tunnel), but I can't leave the
firewall off.  I could open up a couple of specific ports, but it
looks like, no matter what I do, the remote kernel is trying to use
one port that changes every time I connect, making it impossible to
allow connections on specific ports and have any effect.  Any help
would be most appreciated.
