I hadn't read closely enough to spot that it says that _some_ revisions
of the WebCam3 parallel are cpia.  The first step is to determine if
your camera is one of them.

When I boot a 2.4.18 kernel with the WebCam II plugged in, I get the
following (taken from dmesg):

    parport0: PC-style at 0x3bc [PCSPP,TRISTATE]
    parport0: Multimedia device, VLSI Vision Ltd PPC2 Camera

If I cat /proc/sys/dev/parport/parport0/autoprobe, then I get:

    CLASS:MEDIA;
    MODEL:PPC2 Camera;
    MANUFACTURER:VLSI Vision Ltd;
    DESCRIPTION:Parallel Port Camera;
    COMMAND SET:CPIA_1-20;

The cpia_pp driver only registers cameras where the device is class media,
and the command set starts with "CPIA_1".

What do you get from your bootup messages and /proc information when
you boot with your camera plugged in?
