Thanks for this!
I've been experiencing some issues with mod_pagespeed and silverstripe, but it could be Amazon EC2 also.

Was there any other steps to take.
This actually gets pagespeed to load on my silverstripe page, but the images don't load.
It rewrites the path to something that doesn't exist.

Thanks again,

Was facing the same issue. It's about the .htaccess configuration within the "assets/" folder.

Use this .htaccess configuration:

AddHandler default-handler php phtml php3 php4 php5 inc

<IfModule mod_php5.c>
        php_flag engine off
</IfModule>

RewriteCond %{REQUEST_FILENAME} !\.(webp|html|htm|xhtml|js|css|bmp|png|gif|jpg|jpeg|ico|pcx|tif|tiff|au|mid|midi|mpa|mp3|ogg|m4a|ra|wma|wav|cda|avi|mpg|mpeg|asf|wmv|m4v|mov|mkv|mp4|ogv|webm|swf|flv|ram|rm|doc|docx|dotx|dotm|txt|rtf|xls|xlsx|xltx|xltm|pages|ppt|pptx|potx|potm|pps|csv|cab|arj|tar|zip|zipx|sit|sitx|gz|tgz|bz2|ace|arc|pkg|dmg|hqx|jar|xml|pdf|gpx|kml)$ [NC,OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule .* / [F]
