If the ip addresses are all in sequence, you might try defining
ifcfg-eth0-range0 instead: (/etc/sysconfig/ifcfg-eth0-range0)

    IPADDR_START="1.2.3.1"
    IPADDR_END="1.2.3.6"
    CLONENUM_START="2"
    BROADCAST="1.2.3.7"
    NETMASK="255.255.255.248"
    NO_ALIASROUTING=yes

Until yesterday I had eth0, eth1 and eth2 with a primary ip address,
eth1 with a range of 5 addresses, and eth2 with a range of 4 addresses
for a total of 12 ip addresses on 4 subnets on 3 ethernet cards with
3 interfaces and 9 alias interfaces. So I'm pretty sure it works... :-)
