This is already possible.  You set the SCI mask such that non-critical 
SCI's are masked.  I don't think we have a generic way yet for userspace 
to tell the kernel what mask bits to set though.

The big issue however, was that until q2d08a host -> EC communications 
was um, a bit unreliable.  So turning of all the wakeups and then never 
being able to turn them back on was a concern.  Now I think I have that 
under control and we can move toward this type of control.
