This is more sane than you think. g-p-m dims the screen when the user is
idle to save battery power (lots!), so externally stabbing at hal to
change the brightness would be the wrong thing to do here, instead
informing g-p-m of the new ideal un-dimmed brightness would be what the
application would want to do.

Only the bits that make sense, i.e. things that dabble in session stuff.
