This will not work, as the mouse driver doesn't know where to plot the
graphics information in SVGA mode (as not all SVGA modes start at
address 0xA000 (as far as I understand).  <TO BE BRIEF> So you have to
define your own handler and inside the handler plot the cursor to the
screen.  I'm sure other people on this newsgroup can explain it better
than I</TO BE BRIEF>
