Have you considered using the subtitle function ? This will allow you to add text at any point to the bottom of the presentation.
Subtitles can be switched on by default and you can also disable the users on/off control on the options screen, that way your text will always be shown to the user.
If this doesn't do what you want then your only option is to either modify the Javascript, or the XSL template (templates/autoview.xsl) which generates the main presentation.
