Hmmmm:

Hmmmm .... OK, just did that. Do have them installed:
[root@kabini1, /etc, 10:56:29am] 769 % grep -i drm LIST.installed.txt
drm-kmod-9.280208 FreeBSD 9.3 Kernel DRM driver
libdrm-2.4.60,1 Userspace interface to kernel Direct
Rendering Module services
[root@kabini1, /etc, 10:57:09am] 770 % grep -i nvidia LIST.installed.txt
nvidia-driver-340-340.93 NVidia graphics card binary drivers for
hardware OpenGL rendering
[root@kabini1, /etc, 10:57:16am] 771 %
I just 'kldload'-ed drm & nvidia, I'll try again momentarily ....
