LENOVO g470 / g570 / gX70

http://rzr.online.fr/q/lenovo# Upgraded #LinuxKernel 3.2.4+ on #LenovoG470 , add: #WiFi #BroadCom , rm: #SdCard , support: #DsdT #AcpI #deb

I can also share this improved script :

cd /usr/local/src/acpi_call && make KDIR=/usr/src/linux-headers-3.2.0-rc6lenovo-g470+/ install
sh -x /etc/local/bin/fanctrl.sh 
sudo crontab -e
#| @reboot /etc/local/bin/fanctrl.sh

for obscure reasons it failed once rebooted :

"error hd0 cannot get c/h/s values" 

and fails to load :

"/boot/dsdt.aml"

while it it there !

sudo aptitude install linux-headers-3.2.0-2-rt-amd64

Not a SolutioN: had to disable UID and acpi -e … it boots but not OverRide AnyThing
