You can turn on the X benchmark mode, it should show the speed
improvment (I see a 3-4X improvement for certain CPU/Video transfers.)
Also, text mode scrolling should be faster.  Some bioses might set the
memory type registers correctly.  Some do not (mine doesn't.)  There was
a bug in my initial version, in that the memory type was not being set
correctly for the video mem (it was being set to 0, instead of 1 (write
combining).)  The ISA memory hole video mem was being set correctly though.

I don't have time to look at it right now.  Sorry...  Lars is
supporting it though :-).
