It sets the vsync and hsync polarity in VGA video mode setting (MSB and
adjacent bit of port 0x3C2, respectively). This isn't used by terribly
many drivers anymore; real VGA of course, fbdev on a real VGA, and a bunch
of driver initialization code. But I doubt that most of the non-VGA cards
pay much attention to it (well, I say that but I'm only vaguely aware
of what it is/was for; still this may provide some terms to google on).
