Re: sshd ipv6 logging in CentOS4 -- IPv6 at the kernel parameter level

That's why my solution removes the kernel modules responsible for ipv6 - 
either by physically renaming/deleting the kernel module from the disk 
drive (simplest, but doesn't hold over kernel change, and I wouldn't 
recommend it) or by disabling the ipv6 modules in /etc/modules.conf or 
/etc/modprobe.conf (can't remember which is the correct file for 2.6, 
probably modprobe).

If you don't allow the module to load then obviously the kernel is 
not-ipv6 enabled and nothing else will work (all scripts/programs and the 
like determine they're running in a non-ipv6 environment and gracefully 
fail or go back to default ipv4).
