There are occasionally problems in the SMP kernels that don't exist in
the non-SMP kernels, or at least, there have been in the past*. It's
just a failsafe, so that if something is going wrong, you can try to
non-SMP version of the same kernel and see if it makes a difference. I
would leave at least the most recent one or two around, just in case.

* for example, in FC1, I had a problem for a long time where the SMP
kernels crashed my hyperthreading p4, while the non-SMP kernels were
fine. Since then, I'm using an older computer so I don't know if the
problem still exists (but I doubt it).
