There's no way for anyone to know anything about that board and where its connections might go. I absolutely would not connect it to the Pi's DSI connector without first knowing exactly what each of those lines were supposed to do. Just because two things are the same shape and size does not mean that they're intended to work harmoniously together. It's very likely indeed that the end result of plugging one into the other is going to be damage to either the Pi or the display board. Find the documentation or work the circuit out from first principles, but don't just plug the thing in.
Moving past the purely electrical problems, I'll eat my hat if anyone's created a driver suitable for dealing with that board over a DSI connection on a Pi. Even if the display board had been designed to connect to the right pins in the right order, you're almost certainly going to have to write your own driver code.
If you're absolutely determined to recycle the board it may well turn out to be easier to strip the individual components (which it should be easier to find datasheets for) and figure out how to interface them with the Pi's 3.3V logic.
