Does the PMU handle the ADB stuff as > well (think I heard so, but not positive)? 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. -- Joseph P.
