Find the commented-out # kopt line in /boot/grub/menu.lst and modify it.
Do not uncomment it.

The update-grub script will parse that comment and propagate your
options to each kernel command line.

I have a different problem: I have to specify the GRUB 'uppermem' option
in each kernel section, or my office router won't boot.  And there is no
way to make update-grub preserve these :(
