Hi Benno,

Several more thoughts on what is going on with your particular system.
Do you own another monitor with a VGA input?
Whether we like it or not, there are some VGA monitors where the I2C bus fail
after some years due to component degradation.
If you have another monitor, you may want to try that one.
At my place, I did encounter one VGA monitor that behaves erratically with
OpenChrome's I2C bus detection.
It was manufactured by a company I have never heard of, and xserver does not
seem to like it (i.e., EDID related API call fails).
    Second possibility can be a faulty cable.
If you have another VGA cable, you may want to try that one.
    Third possibility can be the mainboard's component degradation, although
this is rather unlikely.
That being said, connector pins do get dirty over time, so if you are able to
"clean" them, it might help you if that really is the cause (somewhat unlikely
in this case).
VGA connector's pins are very hard to clean due to the way the connector is
