Did you also install the X driver for your graphics card?
If you have a Thinkpad, I guess it contains Intel graphics.
What does /var/log/Xorg.0.log say about that?

It would at least solve the ABI incompatibility problem.
Currently I have a system running v12.0-p7 with the following
configuration:

In /boot/loader.conf:

	i915kms_load="YES"

I have installed the xf86-video-intel package for X, and X
starts without any configuration file. I also don't have
anything DRM-related in any of the system configuration files.
But X works as expected.

If you get the latest OS sources and obtain a current ports tree,
things should be in sync again. But don't use pkg to update your
system in such a case without carefully locking the DRM kernel
module port as mentioned before.

Check if all components needed for X are actually installed.
