Are you using synaptics X driver? It can be tweaked to adjust
sensitivity and lots of other things.

Have you tried synclient utility? It temporarily disables the touchpad
when you start typing and re-enables it when you done.

There are ways to disable it:

echo -n "none" > /sys/bus/serio/devices/serioXdrvctl

This should disable it completely.
