Alas I do not have access to the code I was working on (study is
buried in stuff) and I really didn't get that far anyway. But, I got
as far as knowing it is possible to run both the current Makefile
infrastructure and the KConfig infrastructure in parallel. The trick
is to create additional Makefiles (Makefile.kc for example). You just
need to add stubs for the KConfig targets (menuconfig, xconfig, etc).

Once the core KConfig Make infrastructure is in place, it's simply (?)
a case of building all the KConfig files
