Thanks for the tip. With it I dug a little deeper into the filesystem...
The / partition is an ext3 fs with 4KB blocksize (accdg to dumpe2fs). I have
76,064 files in this partition. Assuming that I'm wasting about 1 block per
file, it would equate to 297MB of wasted space. While it is a big pile of
wasted space, it is still not 1.6GB -- there's still 1.3GB that I can't account
for.

Here's an explanation I found in the nets:
difference between disk usage (du) and free blocks displayer (df)
