Reading between the lines in the bug report below, I see mention of Xenomai on the 3.8.13 kernel for the BeagleBoneBlack.
I have also seen mention that TI has the SGX accelerated graphics drivers running on the 3.8.13 kernel. There are probably still some missing pieces to the goal of having Open GL on a real time kernel ready to run LinuxCNC on a BBB, but can someone in the know comment on the current state of things? I will be exhibiting at the NOVA Mini-Makerfair in a couple of weeks and would love to be running it there.
