Uhm, that should be public_html/sites/default/settings.php

> public_html/sites
> public_html/sites/subdomain.mydomain.com (settings.php for the new site)

Yes, that is correct.  Are you using the same DB?  Did you prefix the 
tables with subdomain_?

> public_html/sites/subdomain.mydomain.com/files

You will need to modify your files setting in the administration GUI.

> public_html/sites/subdomain.mydomain.com/modules
> public_html/sites/subdomain.mydomain.com/themes
>

These two are only needed if you plan to use modules and/or themes that 
are not present in the default site.

I don't know about this, I don't use cPanel.

Usually a result of something not configured correctly.  You must 
execute the install.php script manually for the subdomain; i.e. 
http://subdomain.mydomain.com/install.php.

Be sure to check your log and system files.  For debugging, you might 
want to add ``php_value display_errors On'' to your .htaccess file.
