NOTE:  Grub counts installed kernels and OSs from 0.  The first kernel
(2.6.11.7)  is number "0",  the second (2.6.9-1.667) is number "1",
etc.

TIPS:  Change "hiddenmenu" to "#hiddenmenu" to disable the hiding of
menu.  This will allow grub to present a menu of kernels and OSs for
booting.  You should also change the "5" in "timeout=5" to a larger
value to provide you with more time to make a selection.
