I did reinstall the setup on a sarge box and here are the details:
# echo "options ov511 force_palette=15" > /etc/modprobe.d/ov511
# mknod /dev/video0 c 81 0
# chown nobody:video /dev/video0
# chmod 640 /dev/video0
# ln -s /dev/video0 /dev/video
Plug the cam into your usb port!
# aptitude install camserv
You can modify /etc/camserv/camserv.cfg for your needs. Have fun!
