I had/have similar problems with the Intel video driver with 7-STABLE.
Newer versions of the driver tend to fair better.  v2.3.0 of the driver
works the best for me.  OpenGL applications may lock (xscreensaver at
least does) from time to time, yet the system is still accessible
remotely.  Amusingly, the xscreensaver "hack" only needs a SIGCONT to
restore access to the system.  v2.3.1 will consistently lock the system.

To install it, I just updated the port version to 2.3.0 and ran make
makesum before installing.  No other changes to the port are necessary.

Obviously, this is not a true fix, but it does help.
