I'm surprised you've managed to miss the existing interfaces:

   include/linux/regulator/machine.h
   Documentation/devicetree/bindings/regulator/regulator.txt

I saw the interfaces, I just don't know what's the correct thing to
do. I'm leaving Device Tree for the moment. I'm more concerned about
addressing the problem in the AB8500 Regulator Driver and it's
Platform counterpart.

The only thing of interest that I could see was the regulator_init()
call-back. Is this what you were alluding to in the first link?

No.  apply_uV.

I guess we're going to have to take a rain-check until I can find
someone who can translate the documentation for me. I just can't
seem to find even a small paragraph or such which can provide me
with enough information to make any decisions.

It does seem that way, yes.
