I don't think anyone was ever able to get their hands on a K80 to confirm. It's a different ID than the GK110 (0xf0) / GK110B (0xf1). I believe it's referred to as a GK210, but not sure if that's just a marketing thing or if it's actually different.
You can try copying the 0xf1 entry in devinit and seeing what happens. https://cgit.freedesktop.org/drm/drm/tree/drivers/gpu/drm/nouveau/nvkm/engine/device/base.c#n3284 i.e. just add "case 0xf2: device->chip = &nvf1_chipset; break;" However it does seem somewhat likely there would be additional differences, so I wouldn't be extremely surprised if it didn't come up without at least some extracted firmware (which we've never done for that chipset).
