Assuming the mounts are hard, the only way I know of to
force dismounts is to reboot! :=)

There is a trick to get around the df hanging problem.
df gets its information for mounted file systems from
/etc/mtab, so you can edit /etc/mtab to remove the lines
pertaining the file systems from the server which is down.
This will trick df into thinking the file systems are not
mounted, when in fact they are. Unfortunately, a cd to the
file systems from the down server will still hang.
