Well, IcelandDreams, if it's any consolation:
My N810 seems to have woken up on its own some time last night, which ultimately killed its battery. At least, that's what I think happened. (Unless my battery is completely messed up, which I hope not).

That Autolock enabled / disabled popup, unfortunately, appears right underneath (depth-wise) the locked / unlocked popup. Libnotify popups should really be stacked so that I can actually read what's going on.
