Hmm... so it basically works (when you hack the RTC read out of the firmware), but only on reboot for some reason (which makes it way less useful). After a full power off I'm reading only zeroes out until I transition GET_TIME again. My guess would be that these shadow registers are not in the RTC power well... I've talked to Alex and he said that we disable the RK808's main power source in S5, but that devices without an EC (e.g. phones) would likely leave it on. So I guess it's still a good extra workaround to keep in the code, but it will never help on Chromebooks (and there's no point in hacking up our firmware for it).
