After thinking about the problem more, I was able to solve it with two zener diodes and some resistors. It remains to be seen if I can actually trim it well enough to be as nice as the circuit you posted. At the very least, I can empirically determine the voltage/position relationship and draw my own scale for the meter. I'll post a write up, since this is evidently not well documented on the web.
