Nick--

We use edd/dm on RedHat 9 and experienced the same flicker as you describe. 
By switching the color depth from 24 to 16 (in /etc/X11/XF86Config, 
"DefaultDepth" and "Depth" under the "Screen" section) the flicker goes away. 
The reduced color map does not affect us otherwise. 

Hope this helps.
