A quick Google suggests editing /etc/modprobe.d/aliases, and commenting 
out the following line:

alias net-pf-10 ipv6

You can see if IPv6 is enabled/disabled with:

# /sbin/ifconfig | grep inet6

If it returns anything, IPv6 is enabled.

Other suggestions (for other distros too) include editing 
/etc/modprobe.conf to add "alias net-pf-10 off", or editing 
/etc/hotplug/blacklist and adding "ipv6".

I have ipv6 support enabled on my lappy, and it doesn't seem to cause 
any problems, but I might try turning it off.  My gateway (which also 
acts as my caching DNS resolver) doesn't have IPv6 enabled, so perhaps 
that stops it affecting me, who knows.

Cheers
