"I'm curious to see how well the other Gen 2 features work on the D3000's CCD chip. I'm not sure how much of it is software vs. hardware"
I think it's a little of both. Active D-Lighting for example is like it is on the D60. It only has on and off. You cannot select the amount of it and it certainly has no auto mode. I speculate this COULD have something to do with the chip and the D3000 and D60 are the only two cameras with such a crippled version of it.
