How recent is the kernel? Do you have the equivalent of 1.67 of
netinet6/ip6_forward.c in your kernel?

# uname -a
NetBSD 5.0_STABLE NetBSD 5.0_STABLE (FW_MYDOMAIN_COM) #0: Tue Dec 22 08:48:24 EET 2009 amd64

# ident /usr/src/sys/netinet6/ip6_forward.c

    $NetBSD: ip6_forward.c,v 2009/11/14 09:45:53 sborrill Exp $

Which is pullup:

sys/netinet6/ip6_forward.c                      1.67

        Clear cksum flags before any further processing like
        ip_forward does. Many drivers set the UDP/TCP v4 flags even
        for v6 traffic and if the packet is encapsulated with gif,
        the IPv6 header would get corrupted by ip_output.
