Note that OHare in /proc/pmu is still known to be flawky as it seems
not all OHare based pbooks need the same formula. But at least it will
be fixed one day and I prefer indeed keeping that tricky code in a
single location. I do have some code to merge one of these days fixing
calculation for the 2400 for example.

Well, the daemon will still be needed to get the "special" keys on OHare
based powerbooks as I think those don't come via ADB.
