It's been there for a while, I'm not sure if there's a more recent
solution documented somewhere. It presumes Debian, requires building a
few kernel modules for v4l and the UVC webcam driver. (the QuickCam5000
uses UVC) However, it refers to kernel 2.6.24, while 2.6.28 offers UVC
and SPCA webcam support in-tree, may find the relevant modules already
built and installable somewhere.  

It also notes that the device node wasn't created automatically,
mkdir -p /dev/v4l
mknod /dev/v4l/video0 c 81 0
