No need to recompile. Add "nosmp" to your kernel command line on bootup.
You can set maxcpu=1 as well, but it will still be an SMP kernel, with the
assorted logic which keeps processors from stepping on each other. It will make
a small (essentially meaningless) performance improvement on a uniprocessor
machine, to quote myself "measurable but not meaningful" in magnitude.
This was important when we ran on 386-16 CPUs with 8MB RAM, it means essentially
nothing now, other than he should be able to do it.
Stupid question #1: you did look in grub.conf to see that you are booting the
right kernel? That your new kernel is even in grub.conf?
