-The PSB table supplied by BIOS allows for the definition of the number of
-p-states that can be used when running on a/c, and the number of p-states
-that can be used when running on battery. This allows laptop manufacturers
-to force the system to save power when running from battery. The relationship 
-is :
-   1 <= number_of_battery_p_states <= maximum_number_of_p_states
-
-This driver does NOT have the support in it to detect transitions from
-a/c power to battery power, and thus trigger the transition to a lower
-p-state if required. This is because I need ACPI and the 2.6 kernel to do 
-this, and this is a 2.4 kernel driver. Check back for a new improved driver
-for the 2.6 kernel soon.
-
-This code therefore assumes it is on battery at all times, and thus
-restricts performance to number_of_battery_p_states. For desktops, 
-  number_of_battery_p_states == maximum_number_of_pstates, 
-so this is not actually a restriction.
