(manual) patch results in
[ 74.465] (II) LoadModule: "sisimedia"
[ 74.465] (II) Loading /usr/lib/xorg/modules/drivers/sisimedia_drv.so
[ 74.465] (EE) Failed to load
/usr/lib/xorg/modules/drivers/sisimedia_drv.so: undefined symbol:
[ 74.465] (II) UnloadModule: "sisimedia"
[ 74.465] (II) Unloading sisimedia
[ 74.465] (EE) Failed to load module "sisimedia" (loader failed, 7)
I used this file: http://pastebin.com/XkYfxrQy
How can I fix this?

Using this option without the patch fails in working screen. I will
try this again once the patch is successful.
