How to update /boot/grub/menu.lst?

How can I set the ex.: “intel_idle.max_cstate=0” in the boot kernel parameter?

So just want to update /boot/grub/menu.lst, how to do it permanently on SLES 11?

Without using yast.

Or just manually edit the menu.lst file and reboot, and it will be permanent, even after future kernel updates?
