indeed - a little knowledge is very dangerous in this case...

rpm -ivh kernel-2.4.xx-xx

as opposed to 

rpm -Uvh kernel-2.4.xx-xx

-i install creates the new kernel/modules in the correct spot and
updates grub/lilo to reflect the addition...

-U update creams your setup and tries to replace existing kernel/modules
with new and for the most part will render a system unbootable.

Again...this applies to RedHat / dunno about SuSE
