I dunno about the "IPADDR0", "PREFIX0" stuff (in fact, anything with a
"blah0".  An interface has but one IP, one netmask, etc.  If you want
multiple IPs on a NIC you set up an alias such as eth1:1. Try a minimum
config and see if that works:

DEVICE=eth1
BOOTPROTO=static
BROADCAST=192.168.1.255
HWADDR=00:26:18:E4:99:77
IPADDR=192.168.1.1
IPV6INIT=yes
IPV6_AUTOCONF=yes
NETMASK=255.255.255.0
NETWORK=192.168.1.0
DNS1=8.8.8.8
NM_CONTROLLED=yes
ONBOOT=no

(in truth, you don't need the "NETWORK=" or "BROADCAST=" bits
either...they're inferred by the desired IP and netmask).
