Contacting the host was the answer in my case. They accessed the php.ini file that was only available via SSH and not FTP. Took a look myself using SSH (located a nice SSH clinet with a GUI (much easier to use than Putty) and found the file. Also can change out the PHP memory limits to 20 megs. Took a look at phpinfo and the globals are off so Drupal 5.7 is now working.

Also had an issue with clean URL's and that was just a matter of using the correct statements in htaccess located in the root Drupal directory.
