We've been trying to get the wiki in better shape in regards to AMD GPU 
and Intel i915 graphics.  Here are two tables which should be pretty up 
to date (although I suspect some of the newer CPU's need to be added):

https://wiki.freebsd.org/Graphics/AMD-GPU-Matrix
https://wiki.freebsd.org/Graphics/Intel-GPU-Matrix

Also the main wiki has been updated which will hopefully provide some 
insight as well:
https://wiki.freebsd.org/Graphics/

tl;dr version is if you have an AMD GPU or Intel i915 based system, 
installing the "drm-kmod" package should work for you as it will select 
the appropriate kmod for your platform.  Furthermore, there is no need 
to install the xf86-video drivers for these platforms as the modesetting 
driver which ships with Xorg is now the preferred Xorg driver upstream.
