Overview

FreeBSD (as of FreeBSD 6.1) has a fairly well supported port of the DRI Project. The 3d driver for ATI Radeon r200, ATI Rage128 and Intel i915 are stable for me.

Installation

DRI has already been integrated into the FreeBSD main tree and merges are also done regularly. Any recent version of FreeBSD 6.1 and above is good to get started with.

Kernel Modules

/boot/loader.conf 

agp_load="YES"

The DRM kernel module is automatically loaded if its available and the chipset is supported.

X DRI Modules

Install the Xorg DRI modules from ports/ 

[buffy] ~> portinstall graphics/dri
[buffy] ~> pkg_info -W /usr/X11R6/lib/modules/dri/i915_dri.so
/usr/X11R6/lib/modules/dri/i915_dri.so was installed by package dri-6.4.1,2

Intel i915

The Intel i915 support got enhanced after the release of FreeBSD 6.1. Be sure to update your sources to RELENG_6 in case you have problems. I had to use latest RELENG_6 before drm would attach correctly on the HP Compaq dc5100 workstation.
