Hi there
do you have any mention of the new kernel in /etc/grub.conf?

you might find that the default kernel is still the original one in
which case there would be a line like
default=1 in grub.conf
changing this to default=0 might bring up the new kernel on reboot
i have an old dual processor box that boots from the previous kernel
after updates for some reason which i haven't researched
