 I'll need to test again on more recent builds, but I have an amd64
 machine (Dell Optiplex 760) with VGA and DisplayPort on which booting
 netbsd-10 or -current hangs if the DisplayPort LCD display is connected
 but powered off.  Netbsd-9 has no problems booting with the monitor off,
 but the monitor won't wake up when powered on again (but ISTR that that
 is just how DisplayPort is).
 
 I'll see about testing it with the VGA output and see if it behaves
 differently.
 
 It may be a while before I can test with the original system which
 spawned this PR.  Lots of clutter to sort out to get the components
 back within cable's reach of each other.
