Okay. I unplugged the device about 2 hours ago. The cron job was set to add a timestamp every 10 minutes.

Connecting to the device, I see three timestamps. Two from after the power-off, one from power-on (apparently the cron job catches up).

For these two timestamps I still had the USB cable plugged in and an active ssh session. I unplugged the cable, and according to dmesg the device suspended 110 seconds later.

q.e.d.

So now I wonder: how do I wake it up during this suspend? In powerd, I see a rtcWakeUp property, which sounds promising. Anybody ever used it? I can't seem to find a value it accepts (X=0, 1, 100, 20000, all return "can only seem to set it to 0 or 1 However I am not sure what precisely" when running lipc-set-prop com.lab126.powerd rtcWakeup -i X).
