John, thanx for your reply.
Yes, I did read this and modified my grub.conf accordingly. However,
the link you've sent me contains a reference to grub-set-default, which
seems to be no longer part of the grub rpm. This is one part of the
problem. The second one, as mentioned above, is that grub seems not to
preserve the fallback state across reboots.
