Ok, thats better, now the image is filled up with black bars; not nice,
but better than cropped.

I fiddled around a little with the testquickcam-mini-application that
comes with the messenger-kernel-module v1.7. As it seems the module
does not resize the image but changes width and height to the next
values the camera supports. 

If you request the camera data immidiatly after setting it, you get back
the really used values. If you ignore these you get a scrambled image
with wrong wrap-arounds.

So I guess somehow Ekiga "knows" about the right values but handles them
wrongly. On the other hand it still might be possible the kernel module
behaves odd.

Why is Ekiga so picky about the resolution anyways? 

I would like to give some support. My knowledge about v4l is very
limited but I can do some hacks in the module code with some hints and
help.
