I have a RHEL3u3 system using grub that had two kernels installed. The first in the grub.conf was an smp kernel, the second was a up kernel. The default line in grub.conf said 'default=0'. I ran 'rpm -e kernel-smp' which removed the first kernel in the grub.conf. Afterwards, the smp entry was gone from grub.conf, but the default line read 'default=1', which doesn't actually exist.
