If anyone want to look into this, the place to start is 'off_mode'.

I think I've tried enabling that before and something didn't work - don't
remember the details.

Then you need to be sure that the 'off_mode' signalling between CPU and PMIC
(the twl4030) is working.  There is a output pin on the OMAP which
indicates when it is in off_mode (sys_off_mode), and an input pin on the
PMIC which handles that signal. When I last looked into this, I concluded that
the default polarity of the two pins were different, or maybe one was
edge-triggered and the other was level based.  Or something.  But I might
have been wrong.

Then you need to set up some power-management scripts in the twl4030 to turn
regulators off when in off-mode, and back on again for resume.
