I'd like to reorganize this change. I think that the two affected properties should be placed next to each other. I'd also remove the remark about ide-disk at disk-activity, since we're leaving ide-disk, with added reference to disk-activity. How about following: + "disk-activity" - LED indicates disk activity - "ide-disk" - LED indicates disk activity + "ide-disk" - LED indicates IDE disk activity (deprecated), in new implementations use "disk-activity"

The class also introduces the optional concept of an LED trigger. A trigger is a kernel based source of led events. Triggers can either be simple or complex.
