Comment 3 for bug 326449

It was clearly stated in the known issues of alpha4 (http://www.ubuntu.com/testing/jaunty/alpha4#Known%20Issues) that the package is not included.
I myself consider that a stupid decision, because the live cd is the primary way to promote ubuntu (and overall kubuntu with the fresh new kde 4.2) but if the touchpad doesn't work, all you can get from your parent/friend/clients is a bad feedback. I hope there was a very good technical reason to not include that driver, and I hope it will be included in the next alpha release.
Bye all.
