Yes -- in fact, I don't think it's a problem any more, so we can
probably just remove it soon, or just disable it in distro's packaging,
but leave it in CVS.  Maybe we should add some auto* stuff to disable
individual scripts' installation by default.

Doesn't matter -- the machine isn't going to be _running_.  And when it
is running again, we're going to go back to the same governor that we
had before.  So basically, we're talking about ~2 seconds of runtime
that this will effect.

Since that's the case, I'd rather just leave it as "userspace", if only
for the reason that it doesn't _do_ anything.  Less stuff being done
means less chances of having to hack on this again when a bug is
introduced.
