A quick glance at the contents of /etc/init.d and /etc/sysconfig seems
to show that this is the way that system initialization is *supposed* to
work, but it looks that it isn't the way that it *does* work, at least
under FC2.  On my system, /etc/sysconfig contains:
        $ cat /etc/sysconfig
        NETWORKING=yes
        HOSTNAME=amito.localdomain
but lsmod definitely shows that ipv6 *is* loaded.

I got rid of it by adding (as suggested in a later posting) the line:
	alias net-pf-10 off
to:
	/etc/modprobe.conf
        
I *strongly* recommend that you do this.  It speeds up web surfing by a
lot (probably because Doubleclick doesn't handle ipv6 properly), and
seems to speed up the system in general (though I can't even guess why.)
