Apache2 has a slightly different configuration system than the previous version. In addition to the main configuration file (/etc/httpd/conf/httpd.conf), it places the module-specific configuration files into /etc/httpd/conf.d directory. Both PHP4 and PHP5 will add a LoadModule line into httpd.conf at the installation time by default. This line should be moved to /etc/httpd/conf.d/php.conf instead.
