[Solved] Radeon 7950 / X problem

EDIT :

I did a complete reinstall and used xf86-video-ati. When I call startx, I get either a segmentation fault or no screens found.

I think I need to call X -configure, but when I do it prints to the log that their are no devices found. Which is funny because it loads radeon module before printing that.

Heres the log after calling X -configure or xstart : http://pastebin.com/4wg8xLjk

I followed this post in order to get to this point. I believe its a step in the right direction because it allows me to boot with nomodeset (without nomodeset it hangs at boot) and than displays in a high resolution (even with nomodeset it works but with a low res) : https://bbs.archlinux.org/viewtopic.php?id=158161

SOLVED:

1. Follow the forum post I posted above, be sure to add nomodeset when booting (In syslinux press tab on Arch before booting and append " nomodeset" or append it to /boot/syslinux/syslinux.cfg after the last Arch line)
2. Be sure to follow the entire thread, including the chmod
3. delete /etc/X11/xorg.conf and replace it with the following

Section "Device"
     Identifier "Radeon 7950"
     Driver "radeon"
     BusID "1:0:0"    <-- this line is important
EndSection

also install a wm and add it to your .xinitrc with exec
