Match of a lifetime! In the red corner VGA, the underdog. In the blue corner,
the killer of registers, the bane of memory access, the POWER WELL! Who will
win?

This series eliminates the unclaimed register access warning introduced by
the delayed VGA memory disable. And now we actually disable VGA memory decode
on machines where we turn the power well off during init, making it slightly
more probable that vga arbitration will work.

Fixing pc8 entry when the last power well reference disappears is left as
an exercise for the reader.
