This option actually disables VGA probing kernel wide - it essentially
skips all of video.S during boot, and then disallows any drivers that may
depend on that data (VGA console being the prime example).
While I am about 85% sure that probing the missing VGA/VESA registers will
not cause any problems, the values read will be nonsense, and I wanted to
avoid the possibility that any part of the code will blindly use the
returned data without checking it.
The option is triggered off of EMBEDDED, and I felt it would be buried
deep enough to not cause heartburn to the casual user.
