Gazebo, or any other software that needs DRI enabled, can be run from a
chroot, but the chroot should have exactly the same versions in the X
stack in order to have a proper DRI support.

For example, if you are using a Precise system and setup a Trusty
chroot, both using Ubuntu packages, based on my experience, DRI won't work.

That is a good point, and we should mention it in Jon's chroot tutorial.

I ported some of my low-level packages using the chroot approach already, so it is clearly helpful and useful.

But, given the X server issues, I doubt that our UTexas research robot packages can be ported that way. Those packages use Gazebo, rviz and rqt heavily.
