The ipv6 routing stack inside the kernel is a separate being that doesn't share much with the ipv4 stack (in those kernel versions at least), and still lacks some of the nicer features that the iproute interface pretends exists also for ipv6 (especially in old kernel versions). So in general, expect problems if you try to use the more exotic features of ip -6/ip6tables. But in your case the problem is simply that the -generic Ubuntu 8.04 kernels are compiled without CONFIG_IPV6_MULTIPLE_TABLES. You could try the -server kernels instead, they might work for this particular feature.
