I'm having the same problems as you, cmd_, but I rely heavily in
workarounds.

I nailed in my KDE Autostart two desktop files, running this.

xinput set-int-prop 11 "Evdev Axis Calibration" 32 45 4008 121 3978
xinput set-int-prop 12 "Evdev Axis Calibration" 32 45 4008 121 3978

So, I simply assure myself that both eGalax devices (the true one and
the fake one) are calibrated. One feature of xinput values is that you
can set bogus values for a device that doesn't support them, so I use
it.

The place to have these settings is not udev rules; is this:

/usr/share/X11/xorg.conf.d/10-evdev.conf

Copy that file to /etc/X11/xorg.conf.d

Fedora 13 and Lucid share their configuration mechanism: a pure UDEV
mechanism. The technique is easier than you think.

Add to that file these lines and see what happens.

    MatchProduct "eGalax"
    Option      "Calibration"           "45 4008 121 3978"  <--or your calibration data
