(Maybe) better approach to get rid from rename _OSI to XOSI

SSDT-OSYS

This is (another) Windows spoofing patch to activate I2C over HID device for VoodooI2C work. The main different between _OSI to XOSI and SSDT-OSYS is this patch will be set global, so there is a chance to break your working trackpad as some laptop have more than one pointing devices in your DSDT and all of them will be activated and make VoodooI2C attached to wrong I2C Device.

@walechan did you make any progress on it? After some time I still would like to switch from _OSI to XOSI rename :).
