I believe that ch7006 is the only external encoder that's supposed to work, so you're in luck. It sounds like it passes the nv04_tv_identify stage of nv04_tv_create -- perhaps it fails later? Although based on the prints, it's even doing dpms stuff (but it hits _detect a second time... odd). Try booting with
nouveau.debug=debug drm.debug=0xe That should provide a bunch more output as to what's going on. Are you sure that the output isn't there? Can you check in /sys/class/drm? What precisely doesn't work?
