Hi, as blender 2.61 not support older gfx card many people have problems to run cycles on the gpu in the future (rev. 42 573).
I would like to start upload kernel for linux 64 for "Cuda Compute Capability" 1.0, 1.1 and 1.2.
You find your card here:
As the kernel are small i put all in on 7z file at graphicall.org later.
For now i put it on my dropbox account:
You have to copy the kernels in to > /2.60/scripts/addons/cycles/lib
It would be nice if builder from other systems like osx and windows do the same.
