Public bug reported:

We need to support Skylake (SKL) graphics in vivid, but the kernel
driver is not fresh enough for proper support.

For the kernel the plan is to provide a separate driver module
(i915_skl) like for Haswell in quantal and Broadwell in trusty. The i915
driver in 3.19 is buggy and lacking features for SKL, so pulling the
driver from current drm-intel-next-queued branch would provide what'll
end up in 3.21. The i915 drivers will be modified so that only i915_skl
loads on SKL machines, and only there. The driver will get further
updates along the way, and possibly also rebased to a later kernel
release.
