df weirdness

[Stefan Nicolai O'Rear <stefanor@cox.net>]

The numbers speak for themselves:

stefan:~$ df
Filesystem            Size  Used Avail Use% Mounted on
/dev/hda6            -56995908899k  1.0k  0.0k  69% /
/dev/hda7            -2517482356645k  1.0k  0.0k  84% /usr

/dev/hda8            -780491812383k  1.0k  0.0k  88% /home
/dev/hdb1            -351934235768k  1.0k  0.0k  19% /var
/dev/hdb2            -732883846947k  1.0k  0.0k   1% /tmp
/dev/hda2            -2096916525k  1.0k  0.0k  10% /msdos

But, stat(1) works:
stefan:~$ stat -f /home
  File: "/home"
    ID: bffffb4f bffff908 Namelen: 255     Type: ext2/ext3

Inodes: Total: 378624     Free: 271615    

Any clue what's going on?
