Here some additional information

1. Bios Versions:
Running this on the current (old, without BIOS updates) system gives:

sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
8,10
09/25/12

2. Information with ARandR
Installing ARandR shows the system automatic configuration:
Output: DisplayPort-1
Resolution: 1920x1080

It seems that by lowering the resolution to e.g. 1680 x 1050 xorg takes much longer to freeze

3. Attempt with fglrx-amdcccle
Installing fglrx-amdcccle leads the system to chose another automatic configuration
Output: DFP1
Resolution: 1920x1080

In the lower right side of the windows appears a message with "AMD unsupported hardware.
xorg freezes quite quickly.
