I have a webcam that woks with vlc using v4l but don' t work with firefox and kino.
Firefox (on chatroulette.com for example) prompt "Your webcam is showing no"
kino prompt "WARNING: raw1394 kernel module not loaded or failure to read/write /dev/raw1394!"
I have something similar..
Code:

m@marco ~ $ ls -la /dev/raw*
total 0
drwxr-xr-x  2 root root     60 Apr 14 11:51 .
drwxr-xr-x 17 root root   4740 Apr 14 11:58 ..
crw-rw----  1 root disk 162, 0 Apr 14 11:51 rawctl

Thanks.

Done but it doesn' t work. I have the raw driver compiled as built-in in the kernel, does it make difference?

I was under impression this is an external module ... maybe I'm wrong, where in kernel config is raw1394?
