I've been meaning to look into this to see if there's some way to add a
table method.  It's moderately tricky because there's two steppings of
Dothan, and the specs are not obvious to me (they seem to list 4
voltages per frequency point, which is confusing).

Anyway, I have a good collection of /proc/cpuinfos now, so I can pick
through them to see what common elements there are.

I guess it would also be good to get dumps from the ACPI tables.  What's
the best way to do that?
