Yes, you'll just have to boot the UP kernel until you do. It should just be
a matter of repeating the same steps with kernel-smp-devel and putting the
resulting .ko files in /lib/modules/xxx.ELsmp

And actually, I don't think the 586 stuff is needed anymore since as of
CentOS 4.4, the installer uses the i686 kernel unless you specifically
request i586 on the boot line.
