what exactly do you mean, by "50%" and "10%". rtcwake doesn't
wake at all? wakes too soon?

hmm. i think we need to step back a bit.
let's ignore powerd for now -- please disable it with:
# initctl stop powerd
then, let's get rid of spurious wakeups, by turning off
most wakeup events:
# echo 0 > /sys/power/wakeup_events/all
the lid, the power button, and the RTC alarm should still be
capable of waking the system at this point.
# rtcwake --utc -m mem -s 10
