So study the old code until I figure out what should be in the Kconfig, 
what "things" to add for it to build, and what "things" to add until it 
boots.  And the hint as to where to start is...  study the old code.

Right.  Copying the old implementation to the new directory and debugging it 
sounded like something I might be able to do.  Starting from scratch?  Not so 
much.
