Well, I'm still working on getting my touchscreen working. I've mostly been working on getting LinuxICE to work. While looking for some information about linux touchscreen drivers I found this http://gentoo-wiki.com/HOWTO_Car_Computer#evtouch_Driver . The evtouch driver worked for my installation after doing that. However, you may need to add the line "Option "rotate" "ccw"" to your xorg.conf file under the touchscreen device section.
