It would help to know exactly what video card you actually have. I know from experience that a really old ati 128mb card will not do the resolution you are trying to get. This was one of the issue I ran into with the Supergamer and video cards. I had to add a lot of resolutions to cover more cards and people using tv's as monitors. You may try a lower resolution like 1366x768 and see if the flickering goes away. Honestly though, xorg 6.9 was a lot more forgiving and easier to work with but that is my rant.
