Since I got my new Dell Mini 10 a few months ago, my touchpad was recognized as a Logitech Wheel Mouse instead of the Elantech touchpad that it really is. As a result, I was not able to change any touchpad related settings (such as tab-to-click).
This all changed yesterday when Florian Ragwitz wrote patches on this bug report and ALLurGroceries helped be figure out how to apply them on this Ubuntu forum thread. Florian's first round of patches fixed this problem for everyone but me. However, a hack was able to fix the problem for me as well. I expect Florian will soon write a proper patch. It seems likely that these patches will land in Linux kernel version 2.6.34, otherwise they will surely make 2.6.35.
