I guess the "-1 instructs the power manager to use its default." is obsolete?

Done.

The OptionalBool is obsolete.

Just checking: The "value < 1.0 => use default" bit is implemented in powerd,
right?

[Daniel Erat, 2013/02/04 17:31:59]

powerd's behavior is actually std::max(factor, 1.0); I've updated this comment
to reflect that.
