This seems a bit concerning from a forward compatibility point of view.This would not work on new Atoms, which inter mix model numbers.
It would make more sense to assume that future processors would behave
more like the most recent (Sandy Bridge in your case) unless there is
evidence to the contrary.
In the past I did a hack in other software to check the cache sizes to
distinguish the two
for unknown models It's not pretty however.
