Are these the patches Intel developed then kept proprietary for
awhile?  If so, you might not need a Pentium.

If I remember right, Intel claimed that the Pentium improvements in
the compiler also ended up actually speeding up code on a 486, as
well.  That might be worth trying out.

It might also be worthwhile trying this out on a Cyrix M1/6x86, and/or
an AMD K6 when it comes out.
