I'm working on a "double-height" keyboard module that will replace both the keyboard and the touchpad module. We don't have any documentation on the touchpad module other than that it has a different pinout than the other modules and the board ID resistor value.

Even just knowing where the board ID and GND pins were on the touchpad module (the same as for the input modules? or different?) would help my particular use case, since I just want to assure the FW16 EC that the touchpad is "present".
