Why do you need that? Just have the driver always report all 3 events
and have applications decide if they want to use ABS_Z events...
Getting the coordinates goes through ACPI, so it eats up CPU. I think I
remember seeing
up to 15-16% CPU usage with all 3 events.
That is why you probably want to disable it in most cases.
