GPU - RV730XT [Radeon HD 4670] ETA Unkown

Hi Everyone,
I am new to Folding at Home so please forgive me if I am missing something.
I have installed the client on a Debian GDM3, so video drivers are installed and working.
However only the SMP ever does any work. The GPU just sits there saying Ready and Unknown ( see attached image )

So my question is simple ? Why is it not using the GPU and can I make it somehow.
Thanks
Ian
