Can I modify the IPv6 source code to make unloading supported?
If yes, how to modify it?

A little bit offtopic:

does anyone know the state about the work on the ipv*4* module? There
was some rumour some months ago.

Would be nice if some day in the future an IPv6-only Linux box would
be possible.

You could.

In fact, you can unload if you pass "unloading=1" when loading.
But, rmmod ipv6 does not work properly and we cannot insmod ipv6 again.
We've fixed this (and code is in our (USAGI Project 
<http://www.linux-ipv6.org>'s) tree), but kernel panics if we unloaded 
ipv6 module when *any* ipv6 sockets exist.

BTW, Don't you think that if we knew all, we've done it? :-)
