Why stop there?  Why not take a crop that's 1000 x 1500 pixels (1/16th
of a 35mm frame) and compare it to a 1.5 MP camera?


This seems like a pretty odd way of comparing things.  What if I use a
6000 dpi scanner and reduce the crop to 2000 x 3000 pixels ?  Then your
D60 will even look better still.  The point is that your D60 has a
maximum resolution of 2000 x 3000 pixels, for the full frame, while the
Provia film probably tops out at something like 6000 x 9000 pixels per
35mm full frame.  If I wanted to use a disc film camera with it's
approximately 1/4 frame size, I would.  I'm not surprised your D60
capture looks better than a disc film camera image.
