The latest -- 1.5.5rc2 (just released last night) -- has direct "srun my_mpi_application" integration. It's not in a final release yet, but as you can probably guess by the version number, it'll be in the final version of 1.5.5.
We have 1-2 bugs remaining in 1.5.5 that are actively being worked. Once those are fixed (hopefully, in the Very Near Future), 1.5.5 will be released.
