At least to some degree hw accelerated 3d works on the 4.6 i915 driver (which in principle supports up through Kaby lake - I don't yet have anything newer than Haswell).
I anticipate maintaining all the pieces: linuxkpi, drm, i915, amdgpu, amdkfd as ports for the foreseeable future to make maintenance and continued development simpler.
I hope to post a call for testers this weekend or early next week.
