kernel upgrading !!

Hi
i have a 2.8 (HT) cpanel server
my kernel release is : 2.6.9-11.ELsmp ...
i use yum update kernel ...to update my kernel ....

after upgrading ... i reboot my server ...then hit uname -a ...
but i still see the old one !!

i take a look to /etc/grub.conf ( my boot loader is grub ) ...
i found this entry :

# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.
# root (hd0,0)
# kernel /vmlinuz-version ro root=/dev/hda3
# initrd /initrd-version.img
#boot=/dev/hda
default=1
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
title CentOS (2.6.9-22.0.2.EL)
root (hd0,0)
kernel /vmlinuz-2.6.9-22.0.2.EL ro root=LABEL=/
initrd /initrd-2.6.9-22.0.2.EL.img
title CentOS-4 i386 (2.6.9-11.ELsmp)
root (hd0,0)
kernel /vmlinuz-2.6.9-11.ELsmp ro root=LABEL=/
initrd /initrd-2.6.9-11.ELsmp.img
title CentOS-4 i386-up (2.6.9-11.EL)
root (hd0,0)
kernel /vmlinuz-2.6.9-11.EL ro root=LABEL=/
initrd /initrd-2.6.9-11.EL.img
