I attached debug dmesg and xrandr outputs.

I noticed another aspect, I have no video signal on luminance and chrominance
pins (s-video) as I told you but I have video signal on composite video pin
(composite). Anyway the composite video signal is disturbed, I attach a picture
as an example. I have this kind of image on the frame buffer during the entire
boot.

With 3.6 kernel, the luminance/chrominance pins works correctly, even during
boot sequence.
