Steps to Reproduce:
1. Set "radeon" friver in xorg.conf.
2. Set any display resolution in xorg.conf.
3. run startx
X starts in 640x480 resolution and ATI driver rejects any resolutions higher
- monitor : iiyama LS902U Vision Master 1451 (17 pouces)
- graphic card : powercolor x800Xl PCie
- drivers : radeon

That log shows X starting at 800x600, not 640x480.
This might be a BIOS parsing bug that's cropped up before.
My motherboard is an ASUS A8N SLI-Deluxe.
This could be the same problem I reported to xorg:
Adding this option to xorg.conf radeon driver section fixed me up:
Option "MonitorLayout" "TMDS, NONE"
I still see this problem in FC6t3, but at least it now defaults to 800x600
instead of 640x480, so the screen is big enough to see the buttons during
a graphical install :-).
Thanks Tom, if i add your option in my xorg.conf, X starting at 1600*1200. It
very good but now I can't siwtch to 1280*1021 or 1024*768 resolutions ...
This should be fixed as of xorg-x11-drv-ati 6.6.2-4 and later. Please test and
reopen this bug if this is still an issue for you. Thanks!
