How do I make xhost changes stick?

[Tyler Smith <tyler.smith@mail.mcgill.ca>]

Hi,

I'm using Etch with x.org, xdm, and fluxbox. I've discovered that I 
can't open an X windows after I log into root using su, as when I try to 
open emacs to edit a config file. I have to use 'xhost local:' first. 
Not a big deal, but I have to do this everytime I log in. Is there a way 
to make this setting stick between sessions?

Thanks,

Tyler
