Are you sure?  My impression is that they are simply sorting them by
the wafer test results.  If they used an internal fuse, there were no
need for a user-visible BODLEVEL fuse (3.3 V devices could always use
the 2.7 V BODLEVEL then).

The very same happens with CPU frequency classification, for the usual
mainstream CPUs (Pentium, Athlon).
