cpu0: Intel Core 2 (Merom) (686-class), 1862.09 MHz, id 0x6f2

As I said, the CPU will report minimum == maximum, the EST
driver checks for this.

This doesn't mean that you can't change frequency and voltage,
it just says that you have to rely on ACPI and the private information
the BIOS vendor and the board manufacturer got from Intel.
