The page says it does.

From the abovementioned page: "VMGL is available for X11-based guest OS's".

At version 0.1.1, I wouldn't expect too much.

OpenGL is just a display mechanism. If the calculations feeding the
display have to be run in an emulator, this will slow your program down
considerably. 

If your program on the guest OS is already written for X11, can't you
port it to FreeBSD?  Or run it natively and transport the output to your
FreeBSD box via X11?
