I saw another post of yours regarding the webcam, and IIRC it was a usb
logitech quickcam? I have one of those too, and I got it to work with the
qc-usb driver: http://www.ee.oulu.fi/~tuukkat/quickcam/quickcam.html

I'd try to make the device manually first, even though it disappears after
a reboot, and try to configure the webcam, then I'd worry about making
/dev/video0 permanent later.
