Seems I found the answer... easier than I suspected it might be.

Running the cron job as my local user, I make the zenity command like this:

 zenity --info --text="nVidia detected" --title="nVidia detector"\
--timeout=3540 --display=:0.0

It seems I can specify the display in zenity and it will appear on my X
display! :)
