i'd think that it would be more likely the nvram resetting.  But PMU is actually
on ADB.  as far as i know, all direct pmu ioctls (battery query, etc) are sent
to /dev/adb, while interpreted ioctls (like sleep) are sent to /dev/pmu, which
is why /dev/pmu features need kernel support and vary from system to system.

The noodle-scratcher in this is the fact that the keyboard's F-key setting is
maintained post-sleep, while trackpad tapping is always reset.  both being ADB
devs reset upon wake, id think it would get reset.  there could be something we
are missing.
