I've merged the series as is. Once the smoke clears from the Yocto 1.5
release, I'll
factor the fragments out into a common location, there wasn't a window
to do it sooner
and I had been waiting a bit .. but I've given up for now, and it's
better to have this in
the layer for wider use.

Thanks for the nice series, glad to see this fixed up and working.
