Sorry, but there simply aren't 24M sensors. Read the following for an example of how color filter arrays work:

This of course doesn't mean that taking a B&W photo on a 6MP camera results in a 2MP file. You still record all channels and the camera creates a 6MP file. Desaturating (or whatever method you choose) in photoshop then converts all those 6MP into grayscale. You don't somehow automagically lose 2/3 of the pixels, you simply "reinterpret" all the pixels. Or maybe I'm oversimplifying, undoubtedly someone will try to prove me wrong (and I very well may be wrong).

I'm NOT wrong however, about there only being 6 million pixels on a 6MP camera. Only the foveon uses separate R, G and B sensors.

24Msensors, 4 for each pixel.
