On those platforms, you simply can't have good entropy and still have user
accounts on the box with the default hardware. Sorry, the hardware just
doesn't permit it. You would have to set up some secure way to draw entropy
off an external pool, there's just nothing else you can do. (I believe there
are non-x87 platforms that have good timers, just not all of them.)
