Great news: I just unloaded raw1394 and video1394, and loaded them in
that order: raw1394 then video1394. I then asked gm to open
/dev/video1394/0: it worked!

I made the following observations:
* kino opens /dev/raw1394, and is happy without video1394: it doesn't
seem to care about the order;
* gnomemeeting can't open /dev/raw1394 (isn't dma available only on that
device?);
* the image looks much better in kino than in gm; notice that it may be
due to the fact that a lesser quality is set for the device, as the
video stream is supposed to go out on the net, while kino probably asks
the best quality, as the video stream is supposed to be stored&used
locally.

Thanks for your help,
