Comment(by lindi):

 I reverted only 6bf861ed654ff59cdf8829e47d6b7361c40f75ba and I can still
 see the bug on screen and in the output of virtual_size:

 {{{
 lindi at ginger:~$ head /sys/class/graphics/fb0/{stride,virtual_size}
 ==> /sys/class/graphics/fb0/stride <==
 960

 ==> /sys/class/graphics/fb0/virtual_size <==
 960,640
 lindi at ginger:~$ xrandr -o 1
 lindi at ginger:~$ head /sys/class/graphics/fb0/{stride,virtual_size}
 ==> /sys/class/graphics/fb0/stride <==
 960

 ==> /sys/class/graphics/fb0/virtual_size <==
 640,960
 lindi at ginger:~$ xrandr -o 3
 lindi at ginger:~$ head /sys/class/graphics/fb0/{stride,virtual_size}
 ==> /sys/class/graphics/fb0/stride <==
 960

 ==> /sys/class/graphics/fb0/virtual_size <==
 480,1280
 }}}

 Now also /etc/init.d/xdm stop works normally.
