Note, I see this bug between my Natty too... between my Natty netbook and my Gentoo desktop (once the X server upgraded to 1.12.99, and still with 1.13.0. Not sure why, because this computer just has a mouse and keyboard, no touch screen or touchpad to provide exciting new XInput events.) Installing libxi6_1.4.3-3ubuntu1.1_i386.deb from Oneiric-updates works fine (no dependency problems and fixes the bug.)
