You could identify the date of the installation by looking at the date of the /root/install.log.

Information about dmidecode in this page:

Another file create just right after the installation is /root/anaconda-ks.cfg. If none of the files in /root is available, then you can view the date of the default kernel and initrd image located in the /boot directory.

Just make sure the system wasn't upgraded and the kernel wasn't recompiled.

Many choose to solve this by appending some script, that writes the installation date into some file, to the %post section of kickstart.

For rhel4, you may just list the systemid file, i.e.,

ls -l /etc/sysconfig/rhn/systemid
