Default [SOLVED] xorg.conf with HD5870 and 1440x900 resolution


I use openBSD 5.1 stable together with my HD5870 graficcard and want to use 1440x900 on my openBSD workstation, cause I got an widescreen and 1280x1024 looks very unsharp (had the same problem solved in other operation systems like gentoo/debian, with 1440x900 it looks sharp).

Therefore to bring my correct resolution live in openBSD I tried several ways to solve it like:


What I did so far:
1. First, I tried to use vesa with

DefaultDepth 24
        SubSection "Display"
                Viewport   0 0
                Depth     24
                Modes     "1440x900"
to force my resolution. It failed.

2. I had several experience with Debian and Gentoo where
  HorizSync    30-107
        VertRefresh  48-120
solved my problems. Very often if these values were wrong, starting X ends up in blackscreens. But not here in openBSD, here I jump pack to 1280x1024, without blackscreen.

3. I tried to use given ModeLines, with openBSD it also failed with the result, given in 2.

4. I thought about using drivers like I can do it in gentoo/debian like: ati drivers. But they don't really exist here, as far as I know, please correct me if I am wrong. But my first idea was to use vesa, cause it have to work, right?

Here is my logfile



Can u assist me? Is my xorg.conf maybe wrong?
