Exactly what I am trying to do. I just want to stop Myth from setting 
the level, now that I have all corrects pretty close via ivtvctl. I am 
NOT trying to make this a complete solution, but it works for me.

Anduin, thank you for pointing me in the right direction, it seems to 
work fairly well. I have modified the patch slightly based on your 
comment. If this is correct (see below) then you won't hear from me 
again on this subject... :)
