I've managed it using the latest "Linux for Human Beings" (Ubuntu 12.04
LTS, fresh installation on Oracle VirtualBox) as "described" below

1) sudo apt-get install bridge-utils

2) add to `/etc/network/interfaces'

  auto tap0
  iface tap0 inet manual

  auto br0
  iface br0 inet static
          bridge_ports tap0
          bridge_fd 0
          address 10.1.1.1
          broadcast 10.1.1.255
          netmask 255.255.255.0

/tmp/tmpCpwb07bugz

          netmask 255.255.255.0

3) add to /etc/dnsmasq.conf

  dhcp-range=10.1.1.10,10.1.1.20,255.255.255.0,12h

NOTE: From now Ubuntu uses `dnsmasq' out the box and it starts from
      /etc/init.d/dnsmasq.

Sure, my tweaks for dnsmasq.conf were the very minimal

    $ grep -Ev '(^#|^$)' /etc/dnsmasq.conf
    dhcp-range=10.1.1.10,10.1.1.20,255.255.255.0,12h

4) reboot


HINT: If you build `nc_test_master' on 64-bit host like me, fix CC
variable in net/common/current/tests/make.host

   CC = cc -m32

/tmp/tmpCpwb07bugz

   CC = cc -m32

Well, I've got the same results for NC tests (BSD, lwIP) with Linux
kernel 3.0 as I've got yesterday (see Comment #16).
