It does mean that you'll be stuck in single processor mode for now though. (unless you try the experimental 568-smp kernel I put on http://people.redhat.com/davej post-install) The pentium pro should be more than capable of running the 686-smp kernel though (and in fact, I did an install on a 4-way proliant 5000 a few days back, which went fine).
