performance benchmarking at this stage is pretty much pointless,
as the current test kernels are loaded with dozens of debugging
features to catch any problems early-on.  These won't get disabled
until test3 at the earliest.

586 class machines will continue to be supported for FC2, though test1
is broken on these CPUs due to a last minute screwup on our part.
test2 should have this fixed.
