Stupid me: I first tried w/ "gpio = <&gpio0 14 0>;", plugged a key to
notice it was not seen, then looked at the logs to discover what seems
to be an error message. Then, I noticed I was addressing gpio0 (as Jason
also pointer) and thought this was the reason changed it for gpio1. At
that point, I should have tested w/ a USB key but instead looked at the
log to check if the message was still here.

Bottome line: it works! I'll resubmit a v2 later this day.

Thanks again.

Cheers,
