I was able to find an ia64 machine running an old 2.4.19 kernel.  Not
quite the same but I was able to reproduce the problem there.

  rename("b/t", "a/t")                    = -1 ENOTEMPTY (Directory not empty)

Strace on linux-2.4.19 on an ext3 filesystem shows this:

  rename("d", "empty")                    = -1 ENOTEMPTY (Directory not empty)

While on linux-2.6.12:

  rename("d", "empty")                    = 0
