When we tried to add such an attibute in the past, Dmitry rejected it:
http://article.gmane.org/gmane.linux.drivers.platform.x86.devel/1089

Apart from that, what your suggesting doesn't seem very different from
the earlier outcome here. We seem to have reached a generic solution,
where udev would identify input devices that have SW_TABLET_MODE and
make them accessible to the current seat. Then gnome-settings-daemon
can monitor them for evdev events (similar to the udev event
monitoring that would be necessary in your proposal).
