Well, that version wasn't really a good one, due to mistakes in the docs mostly, so a new one follows (with better docs hopefully). Besides, I thought I'd include a patch that exposes ACPI power state information, because it kind of belongs to the lot. It goes as the new [1/4]. [2/4] is the previous [1/3] and so on.
