If you just edit the lilo.conf or grub.conf and set it to use the smp
version of the kernel, then that should work.
For example, if you use lilo then the beginning of your lilo.conf would be
something like
prompt
timeout=20
default=2.6.9-78.0.13.E
boot=/dev/md6
map=/boot/map
install=/boot/boot.b
message=/boot/message
serial = 0,38400n8
linear
image=/boot/vmlinuz-2.6.9-78.0.13.ELsmp
label=2.6.9-78.0.13.E
initrd=/boot/initrd-2.6.9-78.0.13.ELsmp.img
read-only
root=/dev/md1
Then execute this command
lilo -v -v
Then if you have no errors it should reboot fine.
