asus-nb-wmi: Asus Notebooks WMI Driver
Introduce a new driver for Asus Notebooks shipped with a WMI device instead of the old ACPI device. The WMI device is almost the same as the one present in Eee PC, but the event guid and the keymap are different. The keymap comes from asus-laptop module. On Asus notebooks, when you call the WMI device, you always need a 64bit buffer, even if you only want to get the state of a device (tested on a G73).
