I checked the pmu polling routine of pbbuttonsd again and saw that your
power button should already work if the pmu message is 6 bytes long. How
much bytes will be send by the pmu? Only two you wrote in the mail or
more?
In case it sends 6 Bytes pbbuttonsd generates the fake keycode 116 for
the power key. This keycode can then be used inside pbbuttonsd. Set
Sleepkey = 116 and it should work.
If your PMU only sends two bytes, I have to patch pbbuttonsd.
Please send me the contents of /proc/pmu/*.
