There doesn't seem to be support for waking up from a power button
press. Is that in a patch that you didn't send out yet, or are you still
working on that?

The recipient list on this is very trimmed. I'm not sure if this was on
purpose. I'm fine if you want to keep it that way until things settle
down a bit, but eventually the subsystem maintainers will need to see
these, so make sure to Cc them when you think the patches are ready.
