exactly how I did it.

But what puzzles me - and none of the gurus in this thread
seem to have answered my question -
is that I can do it interactively,
but when I put exactly the same commands into grub.conf
they do not work.

WHY IS THIS?

I'm using the standard grub in a standard up-to-date Fedora-13.

Incidentally, you say it can be done.
So why not just give your stanza in grub.conf
that has the desired effect?
