This bug affects me on Dell E6410. I saw only the PS/2 mouse instead of ALPS touchpad in Xorg.log. But Seth's patches from <a href="https://bugs.launchpad.net/ubuntu/+source/linux/+bug/550625">Bug 550625</a> helps, and now my touchpad is fully working (except strange cursor jitter). So these bugs at least related to each other.
