Can't you put your PXE server on a UPS so it will ride out power outages, even if the other boxes don't? This way there will be something alive to respond to reboot requests.

Have you looked at the syslinux stuff maybe? Just a small bootloader that calls into the BIOS reboot vector might be all you need if you can work with that base.
