Removing Wordpress Autosave and Drafts

Another problem with Wordpress that has almost instantly begun to bug me is the autosave 'feature' of Wordpress. I simply don't want it on! There doesn't seem to be an option, and despite downloading a plugin to fix it 'Disable Revisions and Autosave' (by Exper) this doesn't seem to work anymore in WP 2.8, damn.

I have since modified the following files:

commenting the line (as shown):

//wp_enqueue_script('autosave');

This will hopefully stop me having to manually fix the keys of my custom variables in the database...
