Support Optimus machines through WMMX (GH-2)
...
This should finally support machines like the Lenovo Y570. WMMX methods should
be more reliable than direct DSM probing so let's try that before calling DSM
directly.

Add support for WMMX method
...
This should support at least the Lenovo Ideapad Y470 and Y570. It probes the
WMMX method before calling the _DSM method directly since that method should
work for all machines that support the NVIDIA DSM.

bbswitch: Support for legacy _DSM function
...
Newer Optimus laptops seems to use a _DSM method which is quite standard. This
is referred to as "Optimus DSM" in some DSDT files and must be called before the
discrete nVidia graphics card is turned off. Other (older?) laptops use a
different UUID, revision ID and arguments which actually enables or disables a
device. The right _DSM arguments is detected during the module initialization.
