Yes, that is what it appears to be.  There are several ways to fix it, it 
depends on the distribution.  There are two methods for nameing init scripts.  
One method would look something like "S34mythbackend"  this would /S/tart 
mythbackend after everything numbered less then 34 and after everything > 34 
and < or = 99 (the max).  Look in the dir that has the sym links to the 
/etc/init.d/ scripts and you can rename the myth script to S99 to make it 
last, or very close to it.

The other method I am not certain is the same on all systems but it's what 
gentoo uses has a section like the following at the top of the init scripts:
depend() {
        need checkroot hostname
        use isapnp
}
where these are names of other init scripts.  In this case you might have 
"need modules" or whatever init script loads modules on your system.  For 
reference my mythbackend init script includes  "need net" and "use mysql" I 
/believe/ need is mandatory dependencies which, if not met, will prevent the 
service from being started whereas use are desired dependencies.  The desired 
service will be attempted to start first but if it doesn't succeed, your 
service will still try loading.  I believe red hat uses the first method.  
Main thing look at where your modules are loaded and then where your 
mythbackend init script is loaded.

Hope this is helpful.
