Since you express surprise, I would concur that it must not be
what you were thinking, whatever that is.

I believe that Aonix is saying that the software they supply
introduces no drift, and if you see drift you should take it
up with Intel (or Cyrix, or AMD).

Since Aonix does not sell hardware, I don't know how much
further they can go (aside from saying you might also take
it up with DEC/Compaq or Samsung, but they don't support
Alpha the last I heard (drift-free or not)).
