Description Kostas Georgiou 2011-05-05 16:01:36 UTC 
With either DVI port on the card 
cat /sys/class/drm/card0-DVI-I-*/modes
doesn't list 2560x1600

monitor-parse-edid shows 2560x1600 as the preferred modeline so the edid seems correct.

Here is a dump of the card's com. (Firepro 2270)
Comment 2 Alex Deucher 2011-05-05 16:09:16 UTC 
Both DVI ports are single link so they can't drive the monitor at rates faster than 165 Mhz.
Comment 3 Kostas Georgiou 2011-05-05 16:25:09 UTC 
Closing as not a bug in this case
