There are cases where when it's necessary (e.g. given uninitialized NVRAM, the Beige G3 with the 10.2 install CD inserted will update the boot device and restart to boot from it). Restart support was done by wrapping the ppc_exec function in a loop and checking for a restart power off reason. We also need to disconnect all event listeners, since they will be recreated when the machine is re-initialized.
