Hi I've tested multisampled context with disabled GL_MULTISAMPLE and it worked for me like year ago or so. There are talks in web that on some hardware GL_MULTISAMPLE does nothing in multisampled context, and multisampling always enabled (with drivers settings set to application control of MSAA), may be you hit one of those?
