Ok, we currently have drivers for mt9m001, mt9m111, mt9t031, and mt9v022. 
Which letter would you take for them?:-) You'd have to take at least two 
characters like "m0", "m1", "t0", and "v0" but that wouldn't be very 
intuitive IMHO either. Take four characters like m001r16() and it looks 
pretty bad compared to all routines being called mt9m001_*.

I'd say that's subjective (not the latter, but the former):-)
