What do you see when you use this?

The likely issue is that the video timing is not correct for the display. You are likely going to have to modify the Linux Kernel to add the display settings and some code to select that display. FriendlyArm auto detects the display in the kernel code so that it can adjust to each LCD that they offer. The Pi display will not be included in that list.

Touch is not likely to work either unless you have a suitable driver for this. The I2C bus is only 1.8V levels. Not sure what the Pi display uses.

Are you also sure that the connector is configured for DSI and not CSI? You are going to need to dig into the kernel to find out more and make changes to get this to work.
