1 & 2 I can't help you with, although 2 may become easier as a side
effect of my current work.

I've imported DRM and i915 from 4.6-rc5 and am extending the linuxkpi
to support both with minimal changes with respect to upstream. This
update will provide support up through the unreleased Kaby Lake
processors.

https://github.com/iotamudelta/freebsd-base-graphics/tree/drm-next-4.6

Left to my own devices I anticipate having something out for test in
no sooner than 2 weeks or so, as this is just a side project. I'd
welcome assistance plugging the holes in linuxkpi and subsequent
debugging.

I can frequently be found on Efnet on #freebsd-xorg.


Cheers.
