It doesn't have to be that drastic because a kernel update doesn't
overwrite the old one, it just sets the newest as the default in your
grub.conf. Just do the update and reboot at a time when you can test
and if it appears to be worse than before, edit /etc/grub.conf to make
the previous kernel the default (the entries are numbered from 0 at
the top) and reboot again. If updates ever add so many kernels that
you are concerned about space in your boot partition you can
rpm -e the ones that you are sure you won't need again.
