the r600g driver still have to load proprietary microcode into the GPU to enable hardware acceleration. This firmware is usually included in the kernel, but is packaged separately in Debian.

You most certainly are using wheezy's xserver-xorg-core which does not provide xorg-video-abi-6.0 any more, and radeonhd is not available for the newer xorg-video-abi because it has been removed from Debian

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=717500 if mesa provides an OpenCL implementation, it needs to do it by providing an ICD, and not the libOpenCL.so.1 library. The libOpenCL.so.1 must be a ICD Loader in order to allow the co-installation of several OpenCL implementations. There exists several implementation for the ICD Loader. There even is ocl-icd packaged in main that is a free implementation...
in upstream git (which will sooner or later become Mesa 10.0), there now is OpenCL ICD support.

Проблемы такие:
при запуске прикладной программы выдаётся сообщение:
ErrorCode:'-1001'
The error code values are defined in opencl.h It look like your platform is not configured properly. CL_PLATFORM_NOT_FOUND_KHR (-1001) error from clGetPlatformIDs. That's because you do have the dispatcher, but no actual OpenCL drivers.
сейчас так:
cat /etc/OpenCL/vendors/mesa.icd
libMesaOpenCL.so
и вот файла libMesaOpenCL.so нет.
как бы мне донастроить OpenCL?
