Avoiding EUI64 addresses on Ubuntu 12.04

Hi
I'm trying to configure an Ubuntu 12.04 Server VM with static IP addresses.
The config is this:
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto eth0
iface eth0 inet static
address 192.87.38.9
netmask 255.255.255.192
gateway 192.87.38.1
# IPv6 static address
iface eth0 inet6 static
address 2001:610:148:cafe::9
netmask 64
autoconf 0
privext 0
dns-search terena.org
dns-domain terena.org
dns-nameservers 2001:610:1:800a:192:87:106:106
2001:610:188:140:145:100:188:188
Because there is a bug in network-manager, I also set this in
/etc/sysctl.d/10-ipv6-privacy.conf:
net.ipv6.conf.all.use_tempaddr = 0
net.ipv6.conf.default.use_tempaddr = 0
After rebooting I still have the EUI64 address:
eth0 Link encap:Ethernet HWaddr 00:50:56:86:00:0f

Any idea how to get rid of it?
This is a server, and I don't want privacy/security extensions, just
the manually configured address.
Thanks!!!
