disabling laptop mouse pointers in the registry

[jmp]

does anyone know how to disable the pointing device in the keyboard on a laptop through the registry?

for some reason i have no options in mouse under control panel for enabling/disabling the pointer and touchpad. its very strange. i was just wondering if there was a reg key that controls it as i cant find it. also, when i have removed it from device manager it just re-installs itself as a device on reboot.
