I'm affected by this bug, which means my ClickPad is not working properly. The bug-description says, there are patches for this, which can be found here. But when I download the newest version of this, I get an archive with directories and files and I have no idea on how to install this.
The instructions are here: http://www.theorangenotebook.com/2012/02/call-for-testing-clickpad.html
I made a script (based on post linked by sendmoreinfo) to solve this bug.

Hope to be helpful.
