Matt Macy added support for current Intel and amdgpu graphics out of tree for now https://github.com/FreeBSDDesktop/freebsd-base-graphics/tree.... It is up to Linux 4.7. The graphics stuff is MIT licensed and the linuxkpi is re-implemented so it will eventually trickle into 11.x or 12 and/or a loadable module packaged with FreeBSD Ports.
Still lots of rough edges but it's pretty fun to watch and participate.
