People don't like linuxconf, but I never had any problems with it. 
The easy way to do what you want is to 
1). install linuxconf from the 2nd 7.2 RedHat cd
2). use linuxconf to go into the Server Part of the Networking section
3). once there, select alias for ethX ( your nic ) 
4). add the additional IPs. 
exit out of linuxconf and do a /etc/rc.d/init.d/network restart
and you should have your new ips active. 

You can manually enter stuff via the /etc/rc.d/rc.local file. At the 
bottom of the file add:
/sbin/ifconfig ethX:0 xxx.xxx.xxx.xxx
/sbin/ifconfig ethX:1 xxx.xxx.xxx.xxx
etc. 

ifconfig will show you all of your devices. 
The ones with ':X' where X is a number is a IP Alias.
