Loading only necessary modules

[chowse]

Hi,
This is Apache 2.2.11. Are there any modules commented below that shouldn't be? apachectl -t returns "Syntax OK", I don't do any user authentication or foreign languages. I run some cgi scripts, and have tested this config; everything seems to work, but I wanted another opinion.
