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.

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

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

@kecinzer, I have been following your posts in few websites since our laptop DSDT are similar. I am using CLOVER and I tried hard coded in DSDT but no success with the touchpad. It returns i2c bus busy. I think that's related to pin rather than _OSI. I will try to figure it out in next few days and share my progress.
