Yes that's true.  You can't take advantage of a feature unless you can be
assured it's there (which is a deadly assumption when it's Local Bus (of
some time, they aren't all the same) and an PC).  But it will affect the
users perception of GUI use (windows, OS/2, NeXTStep 486).

As I said a similar problem seem to crop up using IDE harddrives.  They
never expected to run them off a bus faster than 8Mhz so never designed them
to handle more than that.
