$ dmesg | grep video
[    1.027256] pci 0000:00:02.0: Boot video device
[    7.318859] Linux video capture interface: v2.00
[    7.611816] uvcvideo: Found UVC 1.00 device Integrated Camera (5986:03b3)
[    7.613572] usbcore: registered new interface driver uvcvideo

... and /dev/video0 exists.

I have a Thinkpad X220 running Squeeze with the same kernel -
3.2.0.bpo.1-686-pae - and the built-in webcam works fine (though its a
different device than the one included in the E520).

I think I am going to explore snapshot.debian.org and see about
installing an earlier kernel and whether or not it makes a difference.
