I wonder if you could put a solenoid controlled bypass line in so at highway speeds the pump pretty much free spins....

You would think they sell one with all the hybrids in development.

(ignoring VW's current woes, other threads have that covered) Most newer TDIs (at least since 2005) have electric assisted steering. At highway speeds it's completely turned off. In the simplest terms its an electric motor attached in parallel to the steering column and controlled by wheel speed. In addition to being a MPG improver, its actually considered a secondary safety feature since it makes it harder to make abrupt inputs at speed.
