  I seriously doubt that my patch would be accepted by MTD as it is a
kludge.  Real "per-partition layout policies" would need to be
designed in.

  Part of me agrees but I'd also like to share what I was forced to do
with the world.  There are probably other folks out there that need to
maintain backward compatibility.  At least this gives them some clue.
I'm still testing these changes so it's too early to say "it works
great".

  I'd like to see it as well.
