If you own one of the Ideal AFCI testers, they are offering a new upgrade for them that will run until June of 2011. They say that they will now be able to trip all the newest C/AFCI's from all manufaturers.
I don't think this means they will be equivelant to the test button on the CB, but at least they will work.
