Fear not, DragonFly 3.6 will have KMS/i915 support out of the box.

I had started to port the FreeBSD drm2 code to DragonFly last year and
Johannes Hofmann made it work, spending many months deciphering various
crashes and fixing the issues one by one.
Finally, Matt Dillon made it possible for it to be fast by implementing
PAT* support in the kernel.

I have just pushed some of the more important commits yesterday.

The rest is available here:

This branch will be slowly cleaned up and pushed in small chunks to
-master in the coming weeks.

The included README file has some setup instructions:
