Read /boot/grub/menu.lst, where it says:

### BEGIN AUTOMAGIC KERNELS LIST
## lines between the AUTOMAGIC KERNELS LIST markers will be modified
## by the debian update-grub script except for the default options below

## DO NOT UNCOMMENT THEM, Just edit them to your needs

If you want every kernel to have a particular option, you set them in
the "automagic kernels list" and run update-grub to actually write them
into the kernel lines further down (which happens automatically for
Ubuntu kernel packages).
