Touchpad buttons don't swap when selecting left handed mouse option [Dell Latitude D620]

Also applies to Dell XPS M1210 laptop which uses a Synaptics touchpad.

Can anyone confirm if this bug only effects Dell laptops?

Laptop sales now exceed 50% of PCs sold, and just about all laptops have touchpads. With 7%-10% of computer users being left-handed, this bug effects between 1 out of 28 potential/actual Ubuntu users, and 1 out of 20.

Same problem on Acer TravelMate 5320.
Always worked perfectly on all earlier versions of Ubuntu, but something has happened on 9.10.
See my Open Question #88706

An equivalent to tubeamp's commandline fix works if I use the correct name for my touch pad, namely,

xinput set-button-map "AlpsPS/2 ALPS DualPoint TouchPad" 3 2 1 4 5 6 7 8 9 10 11 12

(I got the name by running
xinput list | grep 'id=' )

Of course this is not a solution, only a very unsatisfactory workaround ...
which leads to the question:
As long as this bug is considered "low priority",
where can either the xinput command, or an .fdi file that fixes the problem, be put so that the mouse buttons are swapped at login, and the swap is not sabotaged by a dysfunctional gnome-control-center?

Same problem with a Compaq Evo N1000c

This should be fixed in the latest version of gnome-settings-daemon, which will be uploaded to Lucid tomorrow
