When I try to set videomode to 1024x768 or 800x600, real videomode doesn't
changes and is 1280x1024@60Hz. Screen shows at right upper part of display with
nesessary size 1024x768 or 800x600 pixels.

IMHO this is problem in ati driver (when I try to change it to vesa all work
fine). I think, my CRT monitor accidentally detected as LCD, so this line in
config forces Xorg to work properly:
Option "MonitorLayout" "NONE,CRT"
I have experienced what I believe is the same bug with my radeon 7200 and an NEC 17" CRT monitor.
The proposed fix does not do anything. Not using DDC information does nothing except allow 640x480
to work. Problem exists on 6.8.1. (netbsd ports)
