-          This driver uses ACPI INT3403 device objects. If present, it will
-          register each INT3403 thermal sensor as a thermal zone.
+          Newer laptops and tablets that use ACPI may have thermal sensors

+          such sensors, expose the temperature information from these sensors
+          to userspace via the normal thermal framework. This means that a wide
+          range of applications and GUI widgets can show this information to
+          the user or use this information for making decisions. For example,
+          the Intel Thermal Daemon can use this information to allow the user
+          to select his laptop to run without turning on the fans.
