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

@kecinzer this patch should be global, maybe other touchpad device in your DSDT initialized too when try to set SDM1 = zero, so there is many devices activated. Try to eliminate other devices
Yes, my laptop can have also touchscreen. Some people using my config reported that changing method from _OSI to XOSI breaks his touchscreen. So I thinking why is _OSI to XOSI method so bad? It seems to me more compatible and global.
So after many dreamless nights I return to day 0 solution using _OSI to XOSI rename and Windows spoofing.

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