Actually, no it isn't.  But is it really needed in 2012 to support using a
non-SMP i486 kernel on Slackware?  I'm thinking it isn't, and considering
dropping this on the x86 IA32 side, where about the most minimal instruction
set likely to be encountered these days is an Atom or something along those
lines.

Thoughts appreciated on this!  Perhaps a thread on LinuxQuestions.org?
