Disable mouse buttons

[Bradley]

Hello, here is a question I'm sure rarely, if ever gets, asked.

How do I disable some of my mouse's buttons for a specific user?  I have 
a 4 button mouse plus a scroll wheel (which also acts as another button) 
and for one user want to disable all (including the scroll wheel) but 
the left and right buttons.  I am using FC8 with GNOME.

Reason?  We are trying to teach our son how to use a computer but a lot 
of the software doesn't distinguish between the left mouse button and 
some of the others and we want to make it so that if he presses one of 
the extra buttons nothing will happen.  Any ideas or suggestions?

This change MUST NOT affect the other user accounts and must be 
localized to the one user.  Your help is appreciated.
