Well, the current scheme only works because there's a small number of
easily identifiable Enhanced SpeedStep-capable processors which happen
to use the same encoding for the PERF_CTL register. It could get more
complicated in future, and falling back to a table from ACPI may well be
the appropriate solution for many people - though I would like to
maintain the tables in speedstep-centrino so that it isn't dependent on
ACPI.
