You should not need X-Windows.

This means that the VM cannot find that module (to state the obvious... 
sorry!); try copying that module (vm-display-X11.la or 
vm-display-X11.so) into the same directory as the squeak executable. 
Alternatively, you may be having linking problems because you're using 
32-bit binaries. While Squeak won't use this plug-in, for some reason it 
won't start unless it is present.

I would recommend trying the 64-bit binaries: 
http://www.squeakvm.org/squeak64/. I have used this version of Squeak on 
an AMD-64 machine without any problems.

Also note that Squeak currently can't use the dual cores; for now Squeak 
can only make use of one core. I don't know about running multiple 
images with a load balancer though to increase thoughput; I don't think 
that Seaside would support this because it keeps stateful sessions.

I will let somebody else on this list handle this. It may be related to 
trying to run a 32-bit binary on a 64-bit machine.
