disabling ipv6 kernel module

[btb <btb@bitrate.net>]

hello-

i have kernel 2.6.8 - and am having difficulty understanding how to 
properly keep the ipv6 module from loading.

initially, i included it in the hotplug blacklist, along with a few 
others, but this didn't work.  the other modules were not loaded, but 
ipv6 still was.  i believe, if i understand correctly, this is because 
if something asks for it, it will load, even if it's blacklisted w/ 
hotplug.  my problem is that i know there are plenty of process asking 
for it simply because they can, not because they need to.

after many hours of reading about modutils, module-init-tools, rmmod, 
modprobe.d, modprob.conf, and many others, the only thing i could come 
up with was to change the line in /etc/modprobe.d/aliases to:

alias net-pf-10 off

and did an update-modules and a depmod.  this did indeed work, but i 
believe it is not the correct way to do this.  especially since the 
aliases file i had to edit says right at the top 'this file does not 
need to be modified'

what is the proper approach to achieving this?

any insight is greatly appreciated
