I wouldn't advertise support for GL_ARB_multisample until it really works. The OpenGL spec allows one to support the entrypoints without really implementing the feature (sort of like texture compression).
It's not trivial to implement and I'm not sure we even have the technical information needed for doing it with the ATI chips.
The "implementation" in the drivers is "correct" and is required to advertise 1.3. The real problem is that GLX support isn't there. There's no support in glXChooseVisual or glXGetConfig (and in any of the supporting infrastructure) for the multisample enums. There's a couple other problems.
In any case, I'm working on fixing the GLX support.
The point I was trying to make is that if we advertise GL_ARB_multisample in the features table people are likely to think they can do full-scene antialiasing by multisampling with those drivers - and that's not true.
Perhaps change the table entry from "GL_ARB_multisample" to just "multisampling" (and report "no").
