When you have kernel and kernel-smp installed on a freshly installed system, and do rpm -Fvh on the 2.4.20-19.9 UP kernel, the kernel-smp kernel is gone afterwards. (the reason for doing the kernels one at a time is to avoid the change of boot order you'll often get afterwards now).

Yup. Install kernels with -i, not -F, if you don't like the behavior.
