I would guess that option exposes DOS-era VGA support, which is still used by operating systems before they boot. While that shouldn't affect the operation of Linux after it has booted, it might, if it changes the default dithering mode on the hardware and Linux doesn't change it after that.

Now I'm guessing too much.
