It occurs to me that the box I've got had Windows on it at one point, and
its possible wake via IR works only because someone set a wake key pattern
under Windows. And that your box doesn't wake, because it hasn't had a
wake key pattern set yet. We don't have any UI for setting a wake key
pattern just yet... (Or if we do, I'm just not familiar with it).
