Due to this assumption and due to the encoded frequency check during initialization, speedstep-centrino driver fails even on systems that has proper ACPI information to do the P-state transition. The change below moves the centrino-speedstep detection to be used only when table based P-state transition is done. For ACPI based P-state transition, we skip the centrino_cpu identification, and as a result we don't use the bus speed assumption in extract_clock. This change makes speedstep-centrino work on Pentium-M based systems, which have more than 100MHz bus speed.
