yes, that's why there is a ".apply_uV = (_minmv == _maxmv)" in the regulator 
macro.

Sorry, I don't get it. In this case, the board wouldn't boot at all because 
nearly all supplies would be undervoltaged. I just checked and all voltages 
are actually set to the *highest* (max) value. Maybe they aren't changed at 
all?
