(Answering myself here)

The "No matching FBConfig" comes from the application, not Mesa. It seems it's
asking for GLX_PBUFFER_BIT and pbuffers isn't that well supported?

For reference, this is the whole list of visuals asked for:

        int attList[] = {
                GLX_BIND_TO_TEXTURE_RGBA_ATI, True,
                GLX_RENDER_TYPE,   isFloatFormat(texture.format)?
GLX_RGBA_FLOAT_ATI_BIT : GLX_RGBA_BIT,
                GLX_X_RENDERABLE,  True,
            GLX_DRAWABLE_TYPE, GLX_PBUFFER_BIT,
                GLX_X_VISUAL_TYPE, GLX_TRUE_COLOR,
                GLX_CONFIG_CAVEAT, GLX_NONE,
                GLX_RED_SIZE,      bpc,
                GLX_GREEN_SIZE,    (nCh > 1)? bpc : 0,
                GLX_BLUE_SIZE,     (nCh > 2)? bpc : 0,
                GLX_ALPHA_SIZE,    (nCh > 3)? bpc : 0,
                GLX_DEPTH_SIZE,    24,
                GLX_STENCIL_SIZE,  0,
                GLX_DOUBLEBUFFER,  False,
                None
        };
