Is it legal under the minimal editing rules to use in-camera noise reduction? I'm not sure if it involves processing using a separate "null" exposure or something similar that would be illegal.

If it's a setting you choose before you press the shutter button, yes. Otherwise, no.
from the rules: "You may:
*
use any feature of your camera while photographing your entry, with the exception of combining multiple captures in-camera.
Wouldn't a "null" image represent another "capture in-camera" which is used to precess the original? I can't actually remember exactly how it works in the 1DMKII.
The editing rules cover POST processing. Whatever settings you make before you press the button are fair game.
So, anything that involves only one shutter press is acceptable, right? The dark frame applied when High ISO or Long Exposure NR is enabled doesn't count as a second image.
