Also, this series is going to be a lot of refactoring, and I'm
constantly trying to *not* incorporate too many changes, and mostly just
stick to straightforward movement. There's a lot more that should be
done wrt actually hiding this stuff within modules (using opaque
pointers etc) instead of exposing all of the data to all of the
drivers. It just can't all be done at once. This is the first step.
