Comment(by fhn):

 I'm sorry i totally screwed up my wiki syntax.[[BR]]
 Here is my previous post in a more readable version.[[BR]]

 I'm really happy to see some progess in this case :)[[BR]]
 Here are my test results.

 I always used the same sequence of commands:[[BR]]
 Reboot[[BR]]
 Login via ssh[[BR]]
 ssh: declare -x "DISPLAY=:0.0"[[BR]]
 ssh: Xorg -noreset[[BR]]
 ssh: xset dpms force off[[BR]]
 keyboard on hp mini: pessing space to activate display again[[BR]]
 keyboard on hp mini: ctrl+alt+backspace to terminate xorg.[[BR]]
 [[BR]]

 I didn't run any xorg clients (except xset of course). While executing the
 commands above i checked the status of the pci-e bus on another ssh
 session via "lspci -d 14e4:4312 -x"

 lvds.debugging.Xorg.log:[[BR]]
 With lvds.debugging.patch applied the pci-e died right after "xset dpms
 force off". The really interesting thing: pci-e came back to life after
 Xorg terminated!

 lvds.touch.only.channel1.Xorg.log:[[BR]]
 With lvds.touch.only.channel1.patch applied pci-e keeps working.
