Looks like we have all the same, except ofc for the image 4/5 where I can see your trackpad active and mine is not. From your pic number 4, you can see the difference. Under I2C0@15 - VoodooI2CPCIController - TPAD --> You have the VoodooI2CHIDDEVICE , and I don't. Now my idea is that my pc/OSX doesn't recognize / see the satellite Voodooi2chid. (I can see that also from the app Geni2c, look at the screenshots. First screen from GenI2C is from a pc with working trackpad, second screen from GenI2C is from my pc without working trackpad and you can see he doesn't find the satellite). So I guess the problem is to make it work this satellite file.
