Do any AMD 5xxx series cards work with Cycles GPU renderer?

Hi, I have a 5970, but it doesn’t work with Cycles GPU renderer. Do any AMD 5xxx series cards work? If they don’t, does anyone know why? Thanks

OpenCL support still WIP, you can get clay render but all shaders turned off (replaced by default diffuse 0.8 material). Only CUDA (Nvidia hardware) and software CPU mode works with full features.
