Public bug reported:
We need to support Kabylake (KBL) and Broxton (BXT) graphics in xenial,
but the kernel driver is not fresh enough for proper support.
For the kernel the plan is to provide a separate driver module
(i915_bpo) like for Skylake in vivid. The drm/i915 driver in 4.4 is not
recent enough for KBL/BXT, so pulling the driver from current drm-intel-
next branch would provide what'll end up in 4.6. The i915 drivers will
be modified so that only i915_bpo loads on KBL/BXT machines, and only
there. The driver will get further updates along the way, and possibly
also rebased to a later kernel release.
