You will not have hardware accelerated graphics is using Xorg if the 
drm-kmod is not present, which may or may be an issue depending on your 
use-case.  It may also effect power management as well, for example on 
my laptop if I don't load the kmod for my Nvidia GPU I get much worse 
battery life.  So that would be something to look out for.

To help you fix this it would be helpful to provide the following:
1. FreeBSD release (uname -a)
2. Graphics hardware (Intel i915 vs AMD)
3. Additional logging/debugging information.  For example if you can 
provide more context of the error in your logs, and if there are repro
