Except it IS an s-video connector.  I can plug an s-video cable directly 
into it, and it displays just fine.  It is modified in that it has extra 
pins to provide extra capability to a breakout cable.  Both component 
capable nVidia cards I have owned operate this way, as well as another 
three at work.

My old ATI AIW had a 9-pin connector, but s-video was still one of the 
formats supported on the breakout cable.
