yokota ec2542bd97 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.
