The dummy kernel module is still there ...

Yes, it is different what Paul and me described. While aliased devices
(Paul) are widely spread, this is the older route. Using ip from
iproute2 (me) is the modern way and already used to add the IPv6
information to the devices. Unfortunately the init scripts and mainly
the configuration options do not support to add IPv4 IPs to an interface
this way. The aliased devices can simply be added by creating
/etc/sysconfig/network-scripts/ifcfg-ethX:Y configuration files. You
could just copy an existing ifcfg-eth0 to ifcfg-eth0:0 and then changing
the relevant data in there. A "service network restart" will bring you
up the new eth0:0 device. (Attention: be careful if the machine is
remote and you edit these things and restart [stop/start] the network.)
