It works for me too on S12 w/ VIA Nano - at least somehow... I have two
issues with it:

1st: the camera is not detected:

$ dmesg | grep -i cam
[ 3.062601] usb 1-4: Product: Lenovo EasyCamera
[ 7.828202] uvcvideo: Found UVC 1.00 device Lenovo EasyCamera (5986:0241)

$ rfkill list
0: ideapad_wlan: Wireless LAN
Soft blocked: no
Hard blocked: no

2: ideapad_killsw: Wireless LAN

Fn-Esc switches the Camera off and on, but there seems to be no soft
killswitch for it. I have no idea how to parse through acpidump to find
out whether there is some similar device listed or not.


2nd: both Bluetooth killswitches reproducibly disappear when I block
ideapad_bluetooth either via Gnome bluetooth-applet or via rfkill block
1 and subsequently reboot. After the reboot rfkill list shows:

0: ideapad_wlan: Wireless LAN
Soft blocked: no
Hard blocked: no
1: ideapad_killsw: Wireless LAN
Soft blocked: no
Hard blocked: no
2: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no

Powering the machine off and on again restores both killswitches.
Interesting is: this does not happen when I boot into single-user mode,
rfkill block 1 there and reboot. In this case, both killswitches are
back.


regards
Mario
