Summary: bbswitch module

bbswitch is a kernel module which automatically detects the required
ACPI calls for two kinds of Optimus laptops. It has been verified to
work with "real" Optimus and "legacy" Optimus laptops (at least, that is
how I call them). The machines on which these tests has performed are:

- Clevo B7130 - GT 425M ("real" Optimus, Lekensteyns laptop)
- Dell Vostro 3500 - GT 310M ("legacy" Optimus, Samsagax' laptop)

(note: there is no need to add more supported laptops here as the universal
calls should work for every laptop model supporting either Optimus calls)

It's preferred over manually hacking with the acpi_call module because it can
detect the correct handle preceding _DSM and has some built-in safeguards.
