3D CAM,
The chief pilot of Sikorsky assured me that the SAR autopilot is fully certified (I confirmed that the testing was finished about 6 months ago - Oct, 06).
It includes full FLIR and radar integration, so targets from either can be automatically inserted into the FMS and coupled SAR approaches can be shot from them directly. In other words, if the FLIR shows a target, the grids of that target are automatically inserted into the approach coupler. Thus you don't have top worry about losing the radar/FLIR target when you turn on the approach, I would imagine.
