Subject: The following features have been added to the Linux port: Added
 battery level detection and AC/battery detection. Added detached audio mixer.
 Confirmed screen brightness adjustment works.

Also cleaned up DEPENDENIES file, separating FreeBSD and Linux requirements.
Both sections of the file now include full package/port names of
dependencies on both operating systems to make it easy to get all
build requirements, runtime requirements and optional components.
