Look at the shell script /usr/sbin/grub-install. Or, you can download
the stripped down version I use in my scripts.

Source that file, then use the convert_grub_device function:

$ convert_grub_device /dev/hda2

Careful, though. I use it in scripts, so it will exit from your
session. Maybe you'll want to change the "exit 1" to "return 1".
