My evil streak makes me want to do something like this under boot -v, but with a twist... Figure out a vague partity with the Linux numbers and then make sure it reports about 3 times higher along with something like this: "This cpu rates XXXXX (meaningless) bogomips.." .. where the reported number is significantly higher than linux would report on the same hardware... That would serve two purposes... one to undermine the ``benchmark'' and the other to tease the various clueless folks with.
