Yes, first verify that you can get accelerated GPU support working on 
the actual system where you run the X-server. If the nvidia-driver 
-package does not work, install one of the other nvidia-driver-* package 
and try again. Test the graphics with OpenGL applications.

After you can get OpenGL working locally on the system where X11 server 
is running in, next you need to try if you can get AIGLX working. To do 
this I would suggest installing the exact nvidia-driver or 
nvidia-driver-* package (which you installed in system with X11 server) 
inside the jail from where you want to run X11 apps. Aftern this you 
should try starting some OpenGL using app from inside the jail with 
DISPLAY=server:0 and see what happens.

If the AIGLX option did not work, you have another solution that 
requires more work but is way more optimal: VirtualGL. I actually have 
used this succesfully on several occassions. To get it working you just 
need to read the documentation at 
http://www.virtualgl.org/Documentation/Documentation and improvise. 
Requires shell scripting, but very doable. You can install VirtualGL via 
packages or ports.
