[Freesurfer] Any updates on recon-all GPU support?

Anyone manage to successfully configure recon-all to run with -use-gpu for recent cuda toolkit versions? I realize cuda support has ceased over the past few years for Freesurfer, but have there been any successful builds for CUDA toolkit versions 6 and up? I am currently looking to configure cuda support on a Tesla K80 GPU, which is part of a small beowulf cluster, which is working wonderfully with FSL's cuda support. Many moons ago, when gpu support was working, I found the -use-gpu option with recon-all to be significantly faster and more practical (for the user) than the -openmp option (which even on a 150 core cluster has provided limited speedup during batch runs). Curious to hear what others have been doing.
