Disabling IPv6 on *one* network interface in Debian

I'm use the 2.6.26-1-amd64 kernel, and it may be that
"net.ipv6.conf.<interface>.disable_ipv6 = 0" is only supported on newer

Subject: Disabling IPv6 on *one* network interface in Debian

Due to our network setup I have asymmetric traffic occurring (post-IPv4 NAT
result) that can be resolved by disabling IPv6 on one of the server's VLANs.
I removed the IPv6 addresses manually using "ip -6 addr del <IPv address>
dev eth0.<VLAN number>" but that will only last until the next reboot.

Any ideas on how to disable IPv6 on *one* network interface in Debian?  My
google fu has failed me.
