Digital BW, The Print

yes I remember. Still, you shouldn't have to do that, it's really best to print the chart exactly as the eventual files you are printing with the resulting profile will be printed. 
It may work fine though. The way  we always did it was simply convert to multi channel, duplicate twice so 3 channels, then back to RGB. Used to have to do stuff like that all the time to RGB and CMYK, and just made an action.
None of this should be necessary though, has Roy commented?
Frankly I've just stayed with CS3 until I start hearing more "all clear"s from CS4 users. I'm paranoid...

All you can do is try it.
