Hrm, that's pretty surprising. It'd be interesting to know how much of
that is due to the PM core itself and how much of that is from drivers.
For the drivers CONFIG_PM isn't really the option they should be using
in the first place - they mostly want some combination of PM_SLEEP and
PM_RUNTIME for the specific functionality. I'm running some checks now.

Raphael's patch will make this a user visible option in place of raw
CONFIG_PM by default so you'd be able to turn that off.
