It appears that doublescan modes show up with twice the refresh rate that they should in xrandr. For instance, I have the following mode in my xorg.conf Modeline "320x200" 17.00 320 336 360 400 200 203 209 212 -HSync +VSync DoubleScan and in the xrandr output, we see the following: Screen 1: minimum 320 x 200, current 1600 x 1200, maximum 4096 x 4096 VGA-1 connected 1600x1200+0+0 (normal left inverted right x axis y axis) 352mm x 264mm [snip irrelevant modes] 320x200 200.5 While a vertical refresh rate of 200Hz is well beyond the capabilities of my display device, the mode nevertheless works properly: the on-screen display of the monitor shows that it is correctly running at ~100Hz.
