I usually test with xawtv, and it works for me. If vidcat has the option
for the device then you can try that too.
Otherwise have a look at /var/log/messages, there might be something
interesting.
If all else fails, modprobe ibmcam debug=1 and watch your
/var/log/messages. This debug level is not that bad, actually - it will
log only v4l ioctls, so open the device and see what happens.
You should also be able to do the cat test:
# cat < /dev/video0 > /dev/null (or anywhere else)
^C
