At some point you won't have a choice, but until then, there are ways  
to prevent IPv6 configuration on an interface.  Edit the ifcfg-ethX  
file and add:

	IPV6INIT=no

If you are using NetworkManager, you may want to edit /etc/sysctl.conf  
and add these lines:

	net.ipv6.conf.ethX.accept_ra = 0
	net.ipv6.conf.ethX.accept_redirects = 0
	net.ipv6.conf.ethX.autoconf = 0

For each of your ethernet devices.

We have removed the ability to disable loading the ipv6.ko kernel  
module.
