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.
