I have completed a patch which updates to the sys/dev/drm of FreeBSD 9.x current. This patch tested on an x86_64 machine (Shuttle SG45H7) with a Radeon HD 4550 enables hardware acceleration not just fallback to software rendering in Mesa as shown in the Xorg.0.log

I have been told on the irc channel to not email the patch to submit due to its size (100k) and to instead link to it from a git repo. I also need the development account for further work porting GEM and KMS (kernel mode-setting) from Linux. David Shao
