Perhaps I'm misunderstanding you but when in RAW mode with every digital
camera I've used the original data wasn't affected by the white balance
setting on the camera. When in RAW mode with those cameras (most recently
the Nikon D100) any white balance setting could be set,  which one didn't
matter, regardless of how the white balance camera setting the resulting raw
data would be the same. White balance was affected only by the adjustments
made in post-camera editing..

Agreed - but just to be literal, white balance settings *do* affect B&W
conversion; whether they are a major factor just depends on how you're
doing the conversion. Yeah, I usually use extreme moves in Channel
Mixer, often with an additional Curves adjustment layer beneath it. But
the right WB setting to preserve the right channel separation (before
you mix them back down) is important, in my experience.
