After seeing that Google Pagespeed now has a nginx module (https://github.com/pagespeed/ngx_pagespeed), I have created an experimental repository for it.
It is available at https://launchpad.net/~sandyd/+archi...rent-pagespeed
You will have to build it yourself (two lines really), but I would love if some people could test it.
If anyone wants the package sources, see the directions at https://github.com/celenebjvl/nginx-latest-pagespeed
The version number still hasnt been updated, but it matches the current Ubuntu release. I will fix that later This was tested on 12.04 only, I will provide a 12.10/13.04 version later on if I have time
