Is it possible to change the type of an already existing hardware device? I have a built-in touchpad on a Jaunty-based system which is currently listed as a mouse, and thus I can't prevent it from tapping! Here are the specifics (from HardInfo):

Name: ImExPS/2 Generic Explorer Mouse
Type: Mouse (this needs to be changed)
Bus: 0x11
Vendor: 2
Product: 0x6
Version: 0x0
Connected to isa0060/serio1/input0
How can I make this touchpad be recognized for what it actually is?
