Based upon a diff orignally submitted by devin smith, Do two things run the check that the maxfid and the highest reported acpi p_state frequency agree only after actually getting the acpi p_state. Secondly prefer the legacy powernow table over ACPI because machines of this vintage of are likely to have broken ACPI implementations.
