We don't need to care about the format of event. Since it is
configurable,
we just need to understand the internal meaning. So maybe we
need to define the internal event number, which stands for a
special purpose. such as:

001 turn off display
002 inc brightness
003 dec brightness
004 s3
......

Be careful, there has a video extension driver
filed at http://bugzilla.kernel.org/show_bug.cgi?id=1944

But , it is still meaningful to standardize the event format.
