I'm glad I could help.
If you want to clean up a little the method, you can automatically
switch the choice in grub at poweroff :
/etc/rc.local.shutdown :
if [ `uname -r` = 2.6.27-lts ];
then sed -ie s/default\ 1/default\ 0/g /boot/grub/menu.lst
else sed -ie s/default\ 0/default\ 1/g /boot/grub/menu.lst
fi

and automatically reboot when the old kernel is loaded :
 /etc/rc.sysinit , after /boot is mounted :
if [ `uname -r` = 2.6.27-lts ];
       then reboot
fi

don't forget to :
replace 0 by the item corresponding to your new kernel and 1 by the other.
have only one blank space between default and 0/1
replace  2.6.27-lts by the result given by uname -r under your old kernel.
