I wasn't aware of that page, but I don't think there is much new there. Most
of it is from the mjpegtools webpage, which I do know. I did check out the
links on the page, though.
Basically, this all worked in FC4, so either I've forogtten something vital
that I had to do when I installed FC4 or something has changed dramatically.
At this stage I don't know which it is.

I think these are the only relevant lines.

I don't know about the first line, but as you can see the zr36067 module is
loading correctly.
What may be relevant from the url you gave me is
"v4l_bufsize=$number where $number is the size of one buffer
v4l_nbufs=$number where $number is the number of the buffers reserved for the
card
Ideally, (v4l_nbufs * v4l_bufsize) = (totalmem - append= in your lilo.conf)
What I'm using (DC10+) : modprobe zr36067 v4l_bufsize=512 card=2
v4l_nbufs=32 "
but I'm not sure how I am intended to use this. I tried a modprobe with those
settings, which didn't seem to make any difference, but that was after the
36067 had been loaded at bootup.

I am. It is a set of command-line tools, and what I use for the video
processing. I installed the livna package. In the past I have only used
mjpegtools built from the mjpegtools source. That could be relevant.
Just as a reminder, these are the messages I see in a console (with comments
interspersed):

Message from the card was: Invalid argument
