I've given another try, setting the above udev rule and removing the
whole tslib InputDevice section from my xorg.conf file. It works so far.
It seems that whatever InputDevice is defined in xorg.conf for the
touchscreen, X.org defines another one from udev inputs if any, leading
to two X InputDevices competing to handle the touchscreen events. I
don't know X enough to characterize this as a bug or not.
To workaround this problem, disabling either the udev[1] or the
configured[2] device works.
[1] setting the above udev rule with 'ENV{x11_driver}=""'
[2] setting the above udev rule with 'ENV{x11_driver}="tslib"' and
removing the related InputDevice section from xorg.conf
Thanks,
