Kernel doesn't recognize my touchpad?

Hello forum.

I've been trying to get my touchpad to work, and suspect that maybe the kernel doesn't recognize it. Consider the output from running "cat /proc/bus/input/devices":

I: Bus=0017 Vendor=0001 Product=0001 Version=0100

As far as I can see, none of these entries match my touchpad. I have a logitech external mouse connected to the system just to be able to use a mouse, which matches that last entry. But shouldn't my touchpad be listed in this file?
