v3 hardware's packet format is almost identical to v2 (one/three finger touch), except when sensing two finger touch, the hardware sends 12 bytes of data.
This looks mostly similar in substance to the patch I sent, although with some good improvements resulting from your better knowledge of the hardware :) One suggestion below. I'll test as soon as my build finishes.
