Laptops don't generally use the onboard GPU fan controller and thermal sensor
since they usually have a single fan for both the GPU and the CPU.  The fan and
thermal zones are generally exposed via ACPI or a vendor specific control.  For
more info on the power management options in the driver see the page I linked
in comment #1.
