If the same binary runs on a Pentium III but doesn't run on 386SX, my first

the same compiler is building an init and such that runs, that's probably not 
it.

How much memory do you have, and is dmesg showing the OOM killer running?

Have you tried one of the other shells (start with lash and work your way up).
