I believe the differences in battery time are indeed related to the electronics within the screens. The color screens do draw more power and thus cut down overall battery life. As someone else said, even if you show "black and white" on the screen, it's still a color screen internally and is still consuming power associated with it's internals.
In my years of working with laptops, I don't recall a large difference in battery life between active and passive matrix color screens (although there are drastic differences in construction) but my gut feeling is that the passive might be slightly better... But we're talking about a difference of only minutes here... I certainly would give up those few extra minutes of battery for a sharper color image of the active matrix display.. but thats just my opinion.
