Many new laptops (such as the Dell Latitude D620) are including fingerprint readers as authentication devices.

There is an existing framework called 'bioapi' that supports these devices. It includes PAM modules, so you could feasibly use it to authenticate XScreenSaver, GDM, etc.

I have not looked into licensing requirements for the software.
