I'd do a simple edit in %pre - if you wish, you can simply replace the 
menu, though I'm generally a little more conservative.

This has proven effective:

[ -f /boot/grub/grub.conf.orig ] \
	|| cp -p /boot/grub/grub.conf /boot/grub/grub.conf.orig
cat <<. >/boot/grub/menu.extra
title Reinstall Interprise Linux
        root (hd0,0)
        kernel /boot/vmlinuz vga=6
        initrd /boot/initrd
title Kickstart Reinstall Interprise Linux ES (2.6.9-1.648_EL)
        root (hd0,0)
        kernel /boot/vmlinuz vga=6 ks=http://RHEL.demo.lan/ks/ks
        initrd /boot/initrd

cat /boot/grub/grub.conf.orig \
	/boot/grub/menu.extra >/boot/grub/grub.conf
mv -vf /boot/grub/grub.conf.orig /boot/grub/menu.extra ~root
