Mmmm..., this is a restructuring of the algorithms within
the glue code into multiple drivers instead of one and exposing
them all.  It is a bit orthogonal to the intention of this
patch set.  I think it is better that I create a 
separate patch on the glue code on top of this patch set 
to implement this.

Herbert, do you agree with this approach?
