 I had occasion to reboot the i82Q45 machine with the display turned off.
 It appeared to be hung--no signal when the display was turned back on,
 seemed unresponsive to keyboard (even Ctrl-Alt-ESC to drop into DDB).
 The only way to regain control that I could determine was to force a
 power-cycle.
 
 Under netbsd-9 (and -current before the DRMKMS update) there was never
 a problem booting the machine with the display off (although the
 DisplayPort monitor will claim there's no signal when turned on later).
