The one problem with this is that *if* the attacker has the slightest idea
of the hardware, their task is vastly smaller. I trust, for example, that
you don't use Dell's s/n/"express code"; Penguin, not having sold 5
gazillion servers, has the first few digits all the same, for years
(they're being optimistic with s/n's that long).
