OK.  This is strange.
1. I ran "yum update" the other night, and the result was the three entries in 
"/etc/grub.conf" that are shown above.  Actually, that is my entire 
"/etc/grub.conf" file.
2. So, almost by inspiration, I looked at /boot/grub/grub.conf and 
/boot/grub/menu.lst (which as you know is a symlink to /boot/grub/grub.conf)

Guess what?  both of the files in the "/boot/grub" directory have only two kernel 
entries.
Also, "/etc/grub.conf" is it's own file, not linked in any way to what appears on 
the boot menu.

So, how did "/etc/grub.conf" get updated when I ran "yum update"?
Also, did  "/etc/grub.conf" used to be a symlink to "/boot/grub/grub.conf"?  If 
so, why is it not on my system?

Anyway, I'm going to copy the grub.conf that was created when I ran "yum update" 
the other night to where Grub will actually be looking for it.  I trust that I 
will now see three kernel entries.
