Yes, you stand a far better chance of making this hack work with a 66MHz
part.    No the newer std parts are not designed to run with a 66MHz FSB,
you should always order them as /66.  Note that AMD has stopped making
these chips due to low demand for them (with 100MHz boards <$80 USA the
price/performance is usually worth it for most folks.)

I've got about 8 of the T2P4's here and I'm not going to bother with it,
they are all getting replaced with 100MHz boards...  and 450MHz chips
that have now fallen to <$82 US.  And I pick up 1MB L2 cache while I'm
at it :-)
