I thought they used a mixture of MSAA and SSAA in some modes, but SSAA by default. The inability of smoothing alpha textures is not the fault of ATI's HW architecture itself however, but relies on the principle of MSAA itself. There are simple workarounds like applying alpha blending instead of alpha checking, but some developers still have not heard of it.
