OK, looks good to me.
One question though, just to make sure everything is covered :
  Suppose that the resume is the consequence of keypad press. If anybody relied
  previously on "reading the keypad" to know which key was pressed to wakeup the
  SoC, is it still working after your patch ?

And I suppose you can't "convince" your bootloader to behave correctly, can you ?

Cheers.
