These fixes need to be separated out from the cleanups and prepared for
v3.4-rc. We need these as standlone fixes (indepenent of the cleanups)
so they can be applied for 3.4-rc. The rest of the cleanups will have
to wait until 3.5.

I've confirmed these fixes also correct off-mode GPIO ouptut glitches
that I was seeing on n900.
