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).

 which adds some extra appeal to those of us who obsess about things like
 having a book review of an author for each letter in the alphabet.' -- rra
