Yes, I had this with a radeon 9200 on a PC and a 1600x1200 LCD connected via DVI (Did not occur with VGA). I had to tell xorg to ignore edid and I modified each mode line's dot clock to the absolute lowest it would go (down to 2 decimal places). I still had flickering at 1600x1200. I've since replaced it with a Fire GL X1 card and the flicker is completely gone. It seems to be the fact there's not enough bandwidth on a single link DVI cable. I didn't have a dual link to test with so I'm not sure if that helps or not.
