No, it is not as simple as that. If you did this, anyone with a CGA
(and certain other kinds of video cards) would kill you. CONIO is incredibly
slow under those circumstances. What we have now (a mix) is a compromise
that's the fastest on average for all systems. But it still isn't perfect on
all systems (ie, yours.)
