Way back in November '09 we had a discussion about editing the Grub
Menu, which I must have used successfully, but don't think I could have
repeated. Now I have a menu with so many 'old' versions of the kernel
that the bottom entries are off the bottom of the screen box. 

Looking into  https://help.ubuntu.com/community/Grub2

and picking out the needed bits, here is how to trim down that menu
list.

1. in /boot, there are three entries for each revision of the kernel. 


examples: 
abi-2.6.32-25-generic     
initrd.img-2.6.32-25-generic  
vmcoreinfo-2.6.32-25-generic

abi-2.6.35-22-generic     
initrd.img-2.6.35-22-generic  
vmcoreinfo-2.6.35-22-generic

config-2.6.35-24-generic  
System.map-2.6.35-24-generic  
vmlinuz-2.6.35-24-generic

Note there are different files for different versions - improvements I
guess. 

I left the 35-27 and 35-28 versions in. 

2. Move the unwanted versions to somewhere else. 

3. sudo update-grub
Takes a minute or two

4. reboot to prove it works. It did for me.
