There's a whole bunch of stuff that's supported by the software rasterizer in Mesa that isn't supported by all (or most) hardware. Each driver has to enable extensions that it supports. If the right set of extensions is enabled by the driver, the Mesa part of the driver will advertise 1.3. I think the only open-source driver that does this is the R200 driver in CVS.
texmem-branch?
trunk doesn't (DRI CVS 12.03.2003):

Uh...GL_ARB_multisample is one of the required 1.3 extensions. It seems to have gone missing.
