It has been some time since I played with a RH 7.3 box, so I might be speeking out of my ass, but my guess is that the 20 min limit stems from the default dhcp lease time.
I guess some of the old RH network scripts do something funky with your configuration files. IIRC, you can disable this via a variable in one of the /etc/sysconfig/networking/* or /etc/sysconfig/network-scripts/* files. I can't recall which one. Sorry.
