Thanks for the help so far, but any other ideas?
[ Disclaimer: I'm not familiar with that camera ]
If the problem was a missing device node, you should have gotten
something along the lines of "No such file or directory".
Once the module is loaded, what does /proc/devices say? For things to
work, the module must register itself a major/minor device number (81/0
in the case of /dev/video0).
If it *does* show as 81 in /proc/devices, then hopefully /var/log/syslog
(and/or /var/log/messages, depending on your syslog config) should
reveal more; it is possible that the module simply doesn't see/recognise
the camera.
Also, double-check that you're using the correct module...
