  Yah, forcing a module to unload usually yields results ranging from
"won't work" to "system crash".  If something is in use, yanking bits
of it away tends to cause problems.  Problems in the kernel are bad.

  As a test, you can bring the system down to single-user mode and
then try the echo-to-unbind command.  As root, "init 1" will go to
single-user.  At the single-user shell prompt, "exit" will usually
bring you back to the default runlevel.
