... add to that i dont use modules much so i probably hit that 
localyesconfig bug ;-)

btw: mind adding localrandconfig too? It would be a perfect tool to 
randomize all configs except a 'must have' core set of options.

( Or is this already possible via some existing kconfig feature? I
  remember having seen something related, did that ever get
  upstream? A quick grep in scripts/ shows nothing but i might have
  missed it.)
