Now no guarantees that this will work but you could then add the following to your sources list to trick the repository into thinking that you were running 10.10 instead.
sudo remove-apt-repository utouch-team/utouch
Then try to install the package once again by pasting the following into terminal:
deb http://ppa.launchpad.net/utouch-team/utouch/ubuntu maverick main
deb-src http://ppa.launchpad.net/utouch-team/utouch/ubuntu maverick main
sudo apt-get update && sudo apt-get install synaptics-dkms
