Have you found a GoFlight driver or PollyPot profile that works with the 767?

On the PollyPot Forum, someone posted one that sort of works...

I have it on my TODO list to get back to trying to understand how to use that software to modify the config.  It is a bit quirky to work with, but shows promise.  I contacted the person on the forum, but he isn't responding.
