Great, this is the approach I prefer too, but...

Now I'm confused.  Leaving runtime suspended devices alone is what I was
doing in my subsystem but was told not to.  According to

    http://www.mail-archive.com/linux-omap@vger.kernel.org/msg50690.html

"it's generally agreed that _all_ devices should return to full 
power during system resume -- even if they were runtime suspended 
before the system sleep."
