Rendering all faces of a cube shadow map (or any cube map render target really) with one render pass.

Incorrect. What you're talking about is layered rendering, which is part of GL 3.2.

Where GLSL 1.5 and geom for R600?

AFAIK the only thing missing for GLSL 1.5 is geom and that's actually being worked on.
