Agreed. I'm also struggling to see what kind of massively parallel operations need to be done in kernel space in the first place.

Maybe it doesn't have to saturate the GPU to be a win. If you can just banish some cache busting, streaming work, like raid processing, to a tiny sliver of the GPU it could be a win.
