First, make the 3D driver a this specific visual. That will make "new" 3D drivers work with "old" 2D drivers. Second, make the 2D driver mark this visual has having stencil. The memory is there (interleaved with the 24-bits of depth), so we may as well expose it. If there's not a bugzilla for this, could you create one? This will ensure that I get this fixed sooner rather than later. This also helps us get it into a stable Mesa release.
