	Still won't work.  The module is being loaded because one of the
network utilities has referenced it (I've never taken the trouble to
track down exactly which one but "ifconfig" and "ip" are my prime
suspects) and the kernel kmodload'ed it.  By the time the module itself
is done initializing, it's already added link local addresses to all the
active interfaces and hooked into the routing tables.  Plus, there's
what ever that utility (presumably ifconfig, but I don't know for sure)
is doing or has done.  So, it's being referenced as long as that utility
has that open socket and it's going to have multiple references by the
time the utility is done.  Game over.  I seriously doubt you could even
"modload ipv6 ; rmmod ipv6" with no references in-between on a kernel
with no network interfaces configured and be able to get away with it.
