That quickly gets out of my depth.  If there is a 32-bit kernel that 
supports that much RAM, I don't know about it.

But on the other point, I vaguely recall that under the classic LTSP 
setup, there was a provision for using a single NIC.

It could be that your hardware (client and server) indicates that 
classic LTSP is your best fit.

You could sign up for the LTSP mail list at 
http://lists.sourceforge.net/lists/listinfo/ltsp-discuss and probably 
get more expansive and precise advice.
