In KDE, there is ksynaptics, which is capable of configuring various 
aspects of the synaptics driver. One thing it's possible to do with it 
is automatically disabling the touchpad while you're typing, enabling 
it again when you stop typing. This will probably solve your problem. 
Don't know the gnome equivalent for this application.
