    not sure if its compatible or not, but yes you can mix brands and even speeds, the computer will just underclock the faster module to match the slower one. and yes you can have 6GB.

    It will work. You just need to know that your existing 1333 MHz 2 GB stick will be downclocked to match the 1066 MHz 4 GB stick from your Toshiba computer.

    is there a way to do that or is it automatically down-clocking and how to check that?

    It is done automatically. You don't need to check it, but you can always see the speed at which your RAM is operating in "About this Mac" in the Apple menu.
