If you are on 10.6 you probably can support an FBO with a multisampled antialiased render buffer. Do a search for FBO + MSAA. Its a two step process, render to a multisample FBO, then blit to another FBO with a normal texture color attachment for the antialias resolve. That or you can just super sample for hardware that does not support FBO + MSAA.
