Please provide proof of your claims.  where is the security risk?   Johann.  
why exactly do you want ipv6 disabled?  

Personally other than using it now.  i think that it will be a big step 
backwards if we disabled ipv6 by default.  for one thing the DOD has mandated 
that all there systems be running ipv6 by 2008 
http://www.networkworld.com/news/2005/080105-ipv6.html so you will see much 
faster acceleration of ipv6 services and usage within the next year since US 
govt contractors will need to have ipv6 to do there job.
