I believe Xorg 7.5 is available via ports, perhaps upgrading to the most recent version of both Xorg and the Intel driver (2.7.1_3) will remedy some of your issues. I will say that the overall quality of open-source Intel graphics drivers are highly fluctuating it seems. However, the Xorg setup on my Intel-equipped machines is running well, although I don't require extraordinary power. The FreeBSD "team" working on Xorg is rather short-handed, and can't be expected to keep up with the most current developments of either Xorg or the constituent pieces (like the Intel driver). Volunteers are always welcome... -Brandon
