You're not working on one of those.   The OpenSolaris/illumos kernel
has no support for i386, i486 or early Pentiums (I don't remember
exactly where the cutoff for support was in the OpenSolaris code
base at the time of the final release - it's much easier to remember
in Solaris 11 where it's simply "amd64" as the minimum to boot).

uname still reports i386 for backwards compatibility, and because
you can still run i386 binaries, even if you can't boot on an i386
processor.
