You can use the cuSPARSE wrappers and deal.II's SolverGMRES should work out of the box (also compare tests/cuda/solver_03.cu). Currently, these classes don't work with multiple MPI processes or multiple CUDA devices. These are not dumb questions. The CUDA support is pretty new and we should certainly improve the description of its capabilities.
