wakeup on USB keyboard/mouse event does no longer wakeup
This is a clone of http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6974470
When device power management is enabled, USB input devices are placed into a suspended state and may not be able to resume a suspended system.
This was probably introduced in the changeset b9f8177eb4e2 for 6867140 ultra 27 does not resume from either mouse or keyboard event
OpenIndiana #272 may be related.

I have an attempt at fixing this "parked" here:
but I was never able to prove that the fix worked.
I no longer have h/w that regularly reproduces this,
so I'm posting a link in hopes someone else might
be able to finish this up.
