* SNY5001
* This is the ACPI handle for the "Sony Notebook Control" driver under

* It provides several methods within the ACPI namespace, including:
* [GS]BRT [GS]PBR [GS]CTR [GS]PCR [GS]CMI [CDPW GCDP]? GWDP PWAK PWRN
*
* SNY6001
* This is the ACPI handle for the "Sony Programmable I/O" driver under

* It is not yet supported by this driver, but provides control over the
* power to the bluetooth, built-in camera and HSDPA modem devices in some
* laptops, and also allows some control of the fan speed.
