On the RasPI there are two ZIF-Connectors S2 and S5. What are they for?
I looked at the schematics page 4 - F4 to F8 and assume that S5 could be the camera connector mentioned here. S2 could be some kind of display interface, but I'm not quite sure.
Can anyone provide information about this ports and what hardware could be attached?
The S2 and S5 are DSI (display) and MIPI CSI-2 (camera) interfaces respectively.
I don't know of any projects that currently make use of these connectors, but that doesn't mean they don't exist. The Foundation has plans to release a camera later this year, and the new opensource GPU dirvers may allow others to get displays working with the DSI interface.
There are now (as of November 2013) two camera modules available to connect to the S5 header: a regular one and one without an infrared filter on top of the CCD.

They're available for purchase through most of the same distributors that sell the Raspberry Pi.
