While I wasted much of the night trying to reverse the protocol, I realized that what I had come up with was nearly identical to the version 3 documentation. Trying the version 3 protocol with the device, I found that it was nearly immediately functional. It seems that while the initialization procedure has changed, the position report format is identical to previous generations.
My tree[1] currently has a hacked brute-force initialization implementation, although it would probably be nice to figure out what this sequence actually means. Otherwise, it seems support for this device is a solved problem. Feel free to give my tree a try. I'd be interested to know whether it works for you.
