morning.

the same page on amd64 documents EST thus:

         EST         Enhanced SpeedStep found on Intel and VIA
                     processors, offering frequency scaling with
                     numerous positions.

that neatly sidesteps the playing catchup issue of trying to list all
supported models. can we do it that way?
