I have never used ext4 and since Karmic was an upgrade from Jaunty, it 
preserved Grub1....I think.

If you will notice in my post:

"With the Jaunty and Karmic installs I tried copying the grub stanzas 
for Hardy to the respective menu.lst files but got "files not found" 
(approx wording) when I tried booting Hardy. With Hardy I copied the 
Jaunty stanzas and got the same result when I tried to boot Jaunty."

They all gave a "files not found" error.
