B) the Mesa guys are finally turning on the light in their attics and are discussing providing DXT support natively in Mesa ( http://lists.freedesktop.org/archives/mesa-dev/2011-March/005826.html ).
It looks like this will never happen. They merged the floating textures (enabled with the --enable-float configure flag, but Linux distribution are unlikely to enable it) because it was infeasible to provide them in an external library, but the DXT texture support will stay in libtxc-dxtn, at least up until the S3 patent is valid.
