It does. I agree with your points.
Might I politely suggest you consider having a shufty at buildroot.
Since you are "a noob" (although I think after building that we can safely term you "blooded") that will undoubtedly seem like fun. Your new found skills with Make certainly will have a home there.
(Perhaps you could inject KPDF into the make packages, a completely kindle app in the tree, With a completely hand built make, that would be cool, BR supports home-madey makes )
As you can see I really have no answers, only ideas, I appreciate your take on the TC's
I am certain KNC meant well.
In other news if you are up for it I could REALLY use some help getting doom going...
Just a thought.
In answer to your question I'm going to dump some 3 stuff on a 5 straight out of buildroot via the CS 2007q3 and see what happens. LOL.
