Yes but the problem is, that this two cmdline was already entry in the 
orginal. So thats because i have try with two. But anyway my hdmi output is 
already off also with only one cmdline  :-(

And concerning /sys/devices, i have verified this not only with the 
terminal, i could really not found this folder! After lib/firmware/ i could 
not see any other folder with sys or devices??
