Well you can try an intermediate solution.
Rename the mythbackend script to something like z_mythbackend and update 
the scripts using
update-rc.d z_mythbackend defaults
(at least on debian that's how it works)

This would insure that during boot the mythbackend would load last (at 
least on debian it goes by alphabetical order after going by runlevel).
I was doing this at one point as one thing that mythbackend needed was 
being loaded afterwards and the mythbackend startup was always quietly 
Sorry I can't give more Fedora specific help.
