Anssi,

Here is the EDID from Xorg.0.log:

[511268.796] (II) fglrx(0): EDID (in hex):
[511268.797] (II) fglrx(0):     00ffffffffffff00412f000001010101
[511268.797] (II) fglrx(0):     00110103806e3e782ad7b3ae51509423
[511268.797] (II) fglrx(0):     0c4a4721080081800101010101010101
[511268.797] (II) fglrx(0):     010101010101023a801871382d40582c
[511268.797] (II) fglrx(0):     45004e6c4200001e011d8018711c1620

I'm seeing the monitor_name ok. Unfortunately, it doesn't dump the
extension that byte 126 indicates to be present. (the CEA EDID Timing
Extension with the SADs ?) to validate the rest of the content
of /proc/asound/cardX/eld#0.0.

Is there any other way to get the EDID data?
