Aha. I was right. It is a tools issue and a interface that changed.
I made a fix for this in the 3.0 kernel tree some time ago, but
I didn't update the lagging BSPs, and the handoff to a meta-intel
change was missed.

With this change (sorry for the linewraps, I'm out of the office):

i.e. bump the META srcrev and everything is properly configured.
Tom or Darren .. or someone else can make the change permanently in
meta-intel/meta-cedartrail.
