It might be a fairer comparison to rime a cross compilation
of a pmax kernel on an alpha... I seem to remember someone
saying the optimiser on the alpha did a lot more work than
most..
(Unless of course the actual speed metic really is just how long
you have to wait before you can boot your new kernel :)
