Yeah, this needs a new ext enable bit which is flipped on in
st_extensions.c and the relevant i965 file, conditional on the driver
being able to handle >= 16x aniso. (There should be a PIPE_CAP for it
on the gallium end of it. If you don't want to hook it up for st/mesa
that's fine too, I or someone else can handle that one-liner.)
