Load view components in 404 error pages

[eluser]Skateinmars[/eluser]
Hello, I am trying to integrate 404 pages nicely with a website.

Currently I translated the hardcoded strings in the show_404 function, and adapted the layout of the error_404.php file, but I'd like to be able to load views and helpers in this file.

Considering that I can't use the $this variable (which corresponds to the CI_Exceptions class), is there a simple way to do this ?
