  Modified:    sys/i386/i386 cons.c cons.h db_interface.c
               sys/i386/isa/pcvt pcvt_ext.c
               sys/kern subr_prf.c
  Log:
  Implement a simple hook (or hack?) to allow graphics device console
  drivers to protect DDB from being invoked while the console is in
  process-controlled (i.e., graphics) mode.
  
  Implement the logic to use this hook from within pcvt.  (I'm sure
  Søren will do the syscons part RSN).
  
  I've still got one occasion where the system stalled, but my attempts
  to trigger the situation artificially resulted int the expected
  behaviour.  It's hard to track bugs without the console and DDB
  available. :-/
