Test For Dual Channel Mode?

[j.dunning]

I just purchased a new MacBook 2.2 ghz SR. I also bought 4 gb of RAM from Transcend. I was hoping someone might know how to tell or test if its running in dual channel mode. I got 2 x 2 gb sticks that are 667 mhz. They are the same part number but Transcend doesn't sell them in "matched pairs" like Crucial and others do. Anyone got any ideas?

Maybe someone can chime in and say if this command still works properly on the latest and greatest hardware and software from Apple.
