Use a recent version of Nautilus that includes smooth scrolling (introduced in GTK 3 or so). Ubuntu 12.04 and 12.10 have smooth scrolling in Nautilus and other GTK3 apps.
I'm not a programer but I'm not sure it's a gtk+ problem, it seems more like a mouse configuration problem. If you scroll down with the mouse wheel it scrolls jumping 3 lines each little movement you do (sorry I can explain it better, my english...) but if you scroll down by clicking the side bar and dragging it down, the scrolling is perfectly smooth.
What I mean is, it CAN be a smooth scroll, the problem is in the way the scrolling is made trough the mouse wheel. Somebody could do a hack so the mouse wheel somehow "emulates" the sidebar click-and-drag.
This feature is not available in Nautilus, sorry.
