Sorry no success with it. Problems which I don't understand:

1. As discribed in the wiki, randr 1.2 support is already included in X.org 
ver. 1.3, which is working fine
2. Im not able to delete an unwanted mode with xrandr:
root at lisa:~# xrandr --delmode VGA-0 "1920x1200"
X Error of failed request:  BadAccess (attempt to access private resource 
denied)
  Major opcode of failed request:  156 (RANDR)
  Minor opcode of failed request:  19 ()
  Serial number of failed request:  15
  Current serial number in output stream:  16

3. with x.org ver.1.4.2 after every resoltion switch I get a default refresh 
rate of 60Hz (versus 75 Hz in ver. 1.3). I can change it to 75 Hz afterwards 
with xrandr, but that is not what I want.

4. for every xrandr-command i get two short flickerings of my monitor (black 
monitor) with ver. 1.4.2. (not with 1.3), this also happens for every change 
of monitor resolution or at start of a wine application. I guess, my monitor 
does ist, while it is accesed with DDC. Thats why I want to disable DDC 
completely an use my hard coded modes, but the DDC-modes are still there in 
ver. 1.4.2 (working in 1.3) and it seems, that the monitor capabilities are 
verified via DDC for every change of resulution in ver. 1.4.2. (that's why 
the black screen??). Is it somehow possible to disable DDC completely? 
(settings in xorg.conf don't seem to work any longer in ver. 1.4.2)
