A while ago I posted that the combination of nginx and php5 in fastcgi mode was actually working better for me than apache with mod-php5.
In order to help me easily deploy new web hosts that use this setup, I created a tiny package that contains an init script and a configuration file.
Rather than having to manually create these files and symbolic links to make sure the fastcgi server starts, all I now need to do is install php5-fastcgi. The package source is available, so backporting to your $distro $version should be trivial.
As a bonus, I also threw my nginx configuration files for doing easy mass virtual Drupal hosting in doc/examples.
