Previewing Normal Maps in 3DView using Cycles?

Hi, everyone!

Lately I’ve been experimenting a lot with baking maps stuff and getting them to work for an upcoming tutorial series and to use them in the Luke’s Escape short film.

Thing is that while in Blender Render, normals can be previewed in the viewport… I couldn’t figure out how to see them in Cycles without using the Rendered preview.

I’d like to know if it’s possible to see them in the Solid/Textured or Material display modes, like when using Blender Render.

Thank you!
