When I did this, I saw a barely perceptible blink on the power LED;
we do go down, it's just for almost no time at all.  The bug on B2s
is that a wakeup is generated the instant we hit suspend.  (You can
confirm that it is actually suspending with dmesg.)

Maybe I can get them a bit closer together.  There are a set of things
we want to do when we think we're about to suspend, though, and that's
what the two stages are for.  It also serves as a warning to the user,
I suppose -- "if you don't want to suspend, move the mouse now".
