Experiencing the same bug on a ati RV570 [Radeon X1950 Pro] card. kernel 2.6.31.5-127.fc12.x86_64 (fedora 12 x64 live cd). Disabling kms, Xorg has no problem with the EDID. The monitor is a CRT 17", DataVision (detected as Kingston Tech Corporation 16" when kms is disabled, and detected as "unknown" with kms enabled) connected through a vga-to-dvi adapter

Ondrej is the resolution properly detect with kms disabled ? if so please attach Xorg.log of such session. George & Ondrej please test with the following kernel : http://koji.fedoraproject.org/koji/buildinfo?buildID=141560 (download rpm which match your config, i686 or x86-64 and install it with rpm -ivh)
Forget to mention that this is a duplicate of : https://bugzilla.redhat.com/show_bug.cgi?id=533632 I am waiting for you to provide more information before marking it has such.
Yes, it works with KMS disabled - see comment #2.
[quote] Ondrej is the resolution properly detect with kms disabled ? if so please attach Xorg.log of such session.[/quote] There are no problems detecting EDID/getting correct resolutions with kms disabled, see Xorg.0.log from that session in comment #6 Will test with the new kernel as soon as possible
Tested with kernel 2.6.31.6-134.fc12.i686 from the link you mentioned. No joy on detecting EDID Attached the dmesg and Xorg.0.log from the session on this new kernel

may be unrelated, but there was a similar case on fedora forums where a intel card user (Intel 82Q963/Q965 graphics) required "nomodesetting" parameter in order to get the corret resolutions. It may not be limited only to xorg-x11-drv-ati component. The link in question: http://fedoraforum.org/forum/showthread.php?p=1295637
