for what it is worth, I have had similar issues. As I move the mouse (12.10) it frequently jumps to the top of screen. I can only describe this as a 'reset' to top center. I am not running Virtualbox and have tried different mouse configurations ( usb, bluetooth, etc..) On a hunch I tried removing the 'psmouse' module and the 'reset' has stopped. Not sure why psmouse was the cause of this, but wanted to share in case that helps anyone else.
