Get rid of the touchpad while using the mouse

I've been fighting several weeks (and making a huge number of typo's due to that) with the touchpad of my macbook pro on Fedora/Gnome.

I've tested several solutions :

- disable it in Gpointing Device Settings --> fail (it always comes back after a short moment)
- use synclient TouchpadOff=1 --> fail
- creating udev rules : --> fail

ACTION=="add", SUBSYSTEM=="input", ENV{ID_CLASS}="mouse", RUN+="/usr/bin/synclient TouchpadOff=1"
ACTION=="remove", SUBSYSTEM=="input", ENV{ID_CLASS}="mouse", RUN+="/usr/bin/synclient TouchpadOff=0

So the best solution I've found (one that works) is : rmmod bcm5974

Now I'll try to add it into the udev rules too.
