Sorry for loosing the CC.  My mail client fool me sometimes :(
Anyway, I do *have* my kernel recipe in my own meta/bsp layer. I copied 
it from the meta-eldk.
I just wonder why this would not break also for your bsp layer since to 
me it seems wrong to ever use Image as a uImage!?
But I guess you have your reasons.
