Disable tap-to-click feature in Knoopix bootable from CD

[basileus]

I run Knoppix 4.0.2 from CD on laptop (Compaq Presario 716). I created a persistent copy of home directory on HDD. I wonder if there is a way to disable tap-to-click feature of my touchpad and keep it stored, so the system will "remember" this next time I boot from CD?
