I have not found any option in LinearModelFit to delay those calculations. Fortunately, all the ancillary calculations are easy to carry out--it's just a bit of a pain. But any regression with millions of data points is going to take some work :-). (I suppose in MMA 9 you could link to R and use its lm, summary, predict, etc. functions.)
