For some reason, this currently seems to be broken, and nobody has come up with a fix yet. The lcdproc daemon can be configured to turn the display off, and it does turn it off for a bit during shutdown, but the display lights back up as soon as the box finishes powering off... So far as I know, we send the exact same display off packet sequence as windows does, so I can't really explain it. My best guess is that maybe the imon driver needs to be unloaded cleanly (modprobe -r), sending those display off commands in its module_exit() routine, and then maybe it'll stay off, but its just a WAG. Not high on my priority list to poke at it though, but I'd welcome any assistance in determining root cause and a fix.
