Heh, right, I *thought* you knew all about that already... I didn't
read carefully enough. :)

Yeah, I suspect that's probably the issue here. ir-kbd-i2c would need
to allow non-Hauppauge signals through (we could add a knob to the
driver to allow that), and you'd need a custom keymap to map those
signals to input codes.
