A good trick is to set up all of the virtual hosts you need in the
server listening on port 80 (presumably this is your apache-1.3.x
server), and then use mod_proxy to fetch the content from the server
on port 8080 (presumably the apache-2.0.x server).  Something like:

    <VirtualHost *:80>
        ServerAdmin  webmaster at example.com
        ServerName   www8080.example.com
        DocumentRoot "/usr/local/www/www8080.example.com/"  # Not sure if this
                                                            # is necessary
    
        <IfModule mod_proxy.c>
            ProxyPass        / http://www8080.example.com:8080/
            ProxyPassReverse / http://www8080.example.com:8080/
        </IfModule>
    </VirtualHost>
