Default serial console oddities with CentOS Linux release 6.0 (Final)

It seems as if /etc/inittab has undergone some changes. That doesn't seem
to be related to my issues however. I am able to setup the grub.conf (
menu.lst if you like ) to use the serial console ttyS0 at 9600 baud and
the usual bits.

However I can not actually see the GRUB menu at boot time. I see nothing
until the server begins to boot and then I can see everything. However the
grub menu is absent entirely.

My config looks like so :

# grep -v "^#" /boot/grub/grub.conf
serial --unit=0 --speed=9600 --word=8 --parity=no --stop=1
terminal -timeout=30 serial console
title CentOS (2.6.32-71.el6.x86_64)
root (hd0,0)
kernel /vmlinuz-2.6.32-71.el6.x86_64 ro
root=UUID=2396ae8a-7eaa-4690-8701-10fb1b604e21 rd_NO_LUKS
rd_NO_LVM rd_NO_MD rd_NO_DM LANG=en_US.UTF-8
crashkernel=auto rhgb console=tty0 console=ttyS0,9600n8
initrd /initramfs-2.6.32-71.el6.x86_64.img

Everything runs fine, however the GRUB menu is no where to be seen at boot
time. Any ideas ?
