[c-nsp] ipv6 autoconfig & linux

I must be missing something simple with v6 autoconfig - last time I did this 
was with a 7200 and Solaris.

On a 6500 running 12.2(18)SXD7, I have something like:

interface Vlan5
  ip address 163.245.209.2 255.255.255.128
  ip access-group in-vlan5 out
  no ip redirects
  ipv6 address 2001:1470:1F01:3521:1:1:1:1/96
  ipv6 enable
  glbp 10 ip 163.245.209.1
  glbp 10 priority 200
  glbp 10 preempt
end


I have a Linux box attached to that network and in /etc/sysconfig/network I have:

NETWORKING_IPV6=yes
IPV6_AUTOCONF=yes

eth1 comes up with a link-local address and I'm able to ping6 the link-local 
address for Vlan5 however it doesn't get a global address.

I changed ifcfg-eth1 to look like the following to verify v6 connectivity and 
it works but I'd really like to get autoconfig working.  Any pointers?

DEVICE=eth1
ONBOOT=yes
HWADDR=00:50:56:A9:07:F0
BOOTPROTO=static
IPADDR=163.245.209.8
NETMASK=255.255.255.128
IPV6INIT=yes
IPV6ADDR=2001:470:1F01:3521:1:1:1:3/96
