Wolfgang,

I took your work and ran with it...  Although making the evtouch script 
run later in the init process didn't work for me, it made me investigate
the /etc/init/ directory (something to do with upstart?).  Inside there
I found the gdm.conf file.  A simple addition, prior to the gdm binary 
executing, of "/etc/init.d/xserver-xorg-input-evtouch" and all seems
to be working (well give it a couple of days to be sure).
