I have beagleboard xm, with both DVI and s-video connected. With and without your series, kmsprint shows: Connector 0 (45) DVI-D-1 (connected) Encoder 0 (44) TMDS Crtc 0 (47) 1920x1200 154.000 1920/48/32/80 1200/3/6/26 60 (59.95) Plane 0 (32) fb-id: 51 (crtcs: 0 1) 0,0 1920x1200 -> 0,0 1920x1200 (RX12 AR12 RG16 XR24 RG24 AR24 RA24 RX24) FB 51 1920x1200 Connector 1 (48) S-Video-1 (unknown) Encoder 1 (46) TMDS Without your series: # ./kmstest -c s-video Connector 1/@48: S-Video-1 Crtc 1/@49: 720x574i@50.00 13.500 720/12/64/68/- 574/5/5/41/- 50 (50.00) 0x1a 0x48 Plane 0/@32: 0,0-720x574 Fb 53 720x574-XR24 press enter to exit and I have a picture on the display. With your series: # ./kmstest -c s-video terminate called after throwing an instance of 'std::invalid_argument' what(): no modes available To be honest, I'm not quite sure how an unknown-connection output should work (maybe kmstest doesn't handle it right), but the behavior is different.
