openCL on RV610 / HD3200 ?

the driver reports it's possible, but cl::Program::getBuildInfo() returns "link failed"


Is it possible to do openCL computations on a RV610 graphics card ?

It's an on-board ATI radeon 3200.

With a test-program, I can compile just fine for the CPU, but any attempt to build the program for the GPU results in a "link failed". I tried some of the example, and also a tiny one:

__kernel void test(__global float yOut)
    //yOut = get_global_id(0);

Is the card just too cheap, or I am doing something wrong ?

I've attached the openCL info of the graphics-card. It does not have any extensions at all, but I'm not sure how important that is.
