Pbbuttonsd versions before 0.7.3 always search on I2C for the ambient
light sensor, nevertheless the machine has one or not. You have a very new
PowerBook with the ambient light sensor connected to the PMU and it might be
that one of you I2C devices don't like my probing and block the program.
In version 0.7.3 I implemented support for the PMU bases ambient light
sensor and also a small database which hardware is available in which
PowerBook model based on the machine type.
It should not show up again with version 0.7.3 and later.
Best Regards
Matthias
