Preliminary packages of nvidia-cuda-toolkit 3.0 (now supports OpenCL, too) are available at: http://stxxl.ae.cs.uni-frankfurt.de/tmp/582ce36a-592b-4677-9c3b-86ed21603fd9/ OpenCL support needs packages from nvidia-graphics-drivers 195.36.24-2 and will be fully functional with 195.36.24-3 (not yet uploaded). Please give it a try and see if you can build your dependent packages now. Andreas
