Sorry for the lousy reporting. The bug is at least one layer down in devicekit-power. I can't reproduce it. Killing devicekit-power makes it work again.
Note that the correct value is always present in /proc/acpi.... info, even when devicekit-power gets it wrong. $ devkit-power --monitor-detail Monitoring activity from the power daemon.
