I have a 1200x1024 screen,
but the rightmost belt of 300 pixels got damaged in a way they are unusable.
How can I force Xorg to treat my screen as 900x1024 device?

That magic must be put in the "Display" SubSection of the "Screen" Section of xorg.conf. Modes should say "1200x1024" but "Virtual 896 1024" should make the screen smaller. Then you might have to specify "Viewport 0 0" to make the smaller virtual screen start at the left because otherwise it will be centred.
My BIOS has a video scaling option that will make every resolution except the maximum only fill a portion of the screen, but it seems like Xorg ignores it unless I mess around with /proc.

Great things come in tar.xz packages.
