+          This driver provides a P state for Intel core processors.
+         The driver implements an internal governor and will become
+          the scaling driver and governor for Sandy bridge processors.
+
+         When this driver is enabled it will become the perferred
+          scaling driver for Sandy bridge processors.
+
+         Note: This driver should be built with the same settings as
+         the other scaling drivers configured into the system
+         (module/built-in) in order for the driver to register itself
+         as the scaling driver on the system.
+
+         If in doubt, say N.
