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."
