hmm........ Takashi's patch works before, but doesn't work now?

Does that because my new patch for bko#34142 ? Could you please add
acer-wmi to /etc/modprobe.d/blacklist then reboot machine ?

Step:
	- add acer-wmi to /etc/modprobe.d/blacklist
	- shutdown your machine
	- remove AC power and notebook's battery
	- plugin AC power then boot your notebook
	- check the brightness control 


Thank's
Joey Lee
