It looks like some package does not provide libcuda (the library itself is there):
Some requested packages cannot be installed: nvidia-cuda-toolkit-4.1.28-1.mga2.nonfree.x86_64 (due to unsatisfied libcuda.so.1()(64bit)) nvidia-cuda-toolkit-devel-4.1.28-1.mga2.nonfree.x86_64 (due to unsatisfied libcuda.so.1) Continue installation anyway?
