Actually, though he did not specifically state it, I believe Joel is using
Debian.  In the Debian GRUB config file, there are "automagic" sections where
you can set parameters for all GRUB menu items to use.  These are hidden
behind hash marks because they are not valid GRUB lines.

Which brings me to a point for Joel:

Though you don't need to run any program to make GRUB itself use the new file,
if you change the automagic sections, you must run update-grub in order for
the changes to take effect.  Have you done this?
