I applied you patch at the commit 4aeebd and its parents c09cd6, and got the
results of "time xrandr" as follows. But the screen displayed incorrectly after
boot up the patched kernels. You can check the dmesg and image of the screen in
the attachment.

The  "time xrandr" results get at commit 4aeebd:
Screen 0: minimum 320 x 200, current 1024 x 768, maximum 32767 x 32767
eDP1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x
0mm
    1024x768       60.0*+
    800x600        60.3     56.2
    640x480        59.9
