the below workaround is posted elsewhere (in pieces), but may be useful for those experiencing this bug:
I finally came to use it for an old machine (otherwise working karmic perfectly of course) with an old D1751 17" AT&T monitor, after lots of research....
# use 'cvt' to get the modeline below to set for YOUR machine
# commands to set the screen to 1024 X 768 with xrandr, only on the machine required
xrandr --newmode "1024x768_60.00" 63.50 1024 1072 1176 1328 768 771 775 798 -hsync +vsync
xrandr --addmode VGA1 1024x768_60.00
xrandr -s 2
# xrandr seems to work around the issue of the 'barebones' xorg.conf
