Ok, I found the problem with having it autodetect when alpha was always 255 or 0 (diff for material.c enclosed). Now it does what I'd expect with the Zbuffer enabled: some trees obscure others even when they're behind the transparent part of the tree. I think the only thing that's going to fix this particular issue is sorting of the faces.
