This capability would benefit MSM as well.  We're looking into a 
soc-specific implementation using Pat Pannuto's "pseudo" platform bus 
extensions (discussed here http://lkml.org/lkml/2010/8/10/389).  After 
we have something working, I would be curious to see if some common 
functionality could be extracted into a more generic mechanism.
