Thanks, that helps a lot.

OK, so we'll push for a sysfs node that can be used by userspace to
determine the wakeup source.

The article is very interesting, there's certainly a great crossover
with OLPC's "idle-suspend" which is essentially the same thing.
However we have various problems with the current implementation,
meaning that most deployments turn it off. Looks like you are taking
steps to address some of those, I'll try and put some time in this
direction in future.
