  Modified files:
    sys/i386/isa         syscons.c 
  Log:
  A workaround for screen flicker; eliminate some I/O access to the VGA
  chip.
  
  It has been observed that the problem is most apparent:
  
  a) in notebook computers,
  b) and/or in the systems with C&T video chips.
  
  Define the new configuration option SC_BAD_FLICKER in the kernel
  configuration file to remove outb()/outw() calls in question.
