gnome-power-manager is just the daemon. And gnome-power-preferences does
not provide the controls to change the profile. Is there really no better
place to select the profile?

It is no problem to put the line in rc.local. But such things can bring a
lot of troubles later. When there will be relevant preference GUI later, I
will have forgotten this little hack and will wonder why the things are
not working then.
