The main problem is when running "startx" I get an overall grey screen with some colored lines (about 30?) and nothing else. Please see the attached "screenshot" for details. It's seems that the X server is crashing and falling back to the console because typing "reboot" blindly when having the grey screen really does a system reboot. The funny thing is that nothing gets logged when running "startx" so I can't really trace the problem.

When I try to run "Xorg -configure" all it does is flicker about two times and then completely freeze the system with a black screen and a not even blinking cursor.

Make sure you have the kms enabled drm loaded before X starts and that
your ddx (xf86-video-ati) is compiled with kms support.  Check dmesg
as well.  Your xorg log shows that the ddx is loading in ums mode
which will cause conflicts of kms is also active.
