What does strace tell you about the statfs system call that df uses to
find out the space information?  For example, here's what I see on my
box running coreutils 5.2.1:

$ df . -h -T
Filesystem    Type    Size  Used Avail Use% Mounted on
/dev/hda5     ext3     68G  7.8G   56G  13% /home
$ strace df . -h -T 2>&1 | grep statfs
statfs("/home", {f_type="EXT2_SUPER_MAGIC", f_bsize=4096, f_blocks=17578039, 
f_bfree=15549458, f_files=8929280, f_ffree=8451951, f_namelen=255}) = 0
