Sorry for being inactive, for some reason I did not get any emails about this thread.
Apparently, acidanthera's version is conflicting with something I did not find yet and causes the touchpad not to work on restarts (on my E7250 at least). I am assuming it is due to the high IOProbeScore. I lowered it, which hopefully fixes it.
Additionally, I changed the VoodooInput processing code, so the kernel panic that most V8 users were getting should be now gone. One of the benefits that V8 users are also getting is using 4 fingers natively. Currently, on 2+ fingers, virtual fingers were created to support touchpads that did not support the third and fourth packet and therefore causing issues with 3 or 4 finger gestures. However, I cannot verify if that's actually the case, as I don't have a V8 touchpad.
Feedback about this kext would be helpful

And yes, like on other touchpads, there is a delay between keyboard and touchpad movement. But this can be changed inside the VoodooPS2Trackpad Info.plist: https://github.com/SkyrilHD/VoodooPS2/blob/x_avg-free/VoodooPS2Trackpad/VoodooPS2Trackpad-Info.plist#L80-L81
