Are you filing bugs about this, or are we just debugging your hand-made
distribution?

There's a test call cheese-test-monitor in the cheese sources which you
can use to debug your problem. The device monitor code uses udev to
enumerate devices. Attach the output of "udevadm info --export-db" so we
can see if the camera is detected properly.
