I am replying to myself in order to save time for people who would try to help me. The source of this odd df output is the reserved blocks that the ext3 file system makes for the super user. I do not currently know why they ended up different on the two file systems I created, because I created them with the defaults. One of the file systems I expanded and then reduced, so perhaps the reserved percentage was altered by e2fsadm. At any rate, in case anybody has the same problem, they can refer to the answer I gave myself :) Thanks!
