Nope.
Nothing gets logged when I press the rfkill...

I'd say that the rfkill rewrite killed my wireless :-(

Bluetooth works at it whould, but not the wireless

But now I have atleast found one way to get it working...

I've built the rfkill utility, and with it I can get the wireless working...

Here is the output when wireless works:
[root@tmb-laptop rfkill]# ./rfkill list
0: acer-wireless: Wireless LAN
	Soft blocked: no
	Hard blocked: no
1: acer-bluetooth: Bluetooth
	Soft blocked: yes
	Hard blocked: no
2: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: no

Pressing the rfkill button gets me this:
[root@tmb-laptop rfkill]# ./rfkill list
0: acer-wireless: Wireless LAN
	Soft blocked: yes
	Hard blocked: no
1: acer-bluetooth: Bluetooth
	Soft blocked: yes
	Hard blocked: no
2: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: yes

And pressing it again gets this:
[root@tmb-laptop rfkill]# ./rfkill list
0: acer-wireless: Wireless LAN
	Soft blocked: no
	Hard blocked: no
1: acer-bluetooth: Bluetooth
	Soft blocked: yes
	Hard blocked: no
2: phy0: Wireless LAN
	Soft blocked: yes
	Hard blocked: no

And after that I cant get wireless back until I again do a:
./rfkill unblock 2
(works only when acer-wireless is no/no and Wireless LAN is yes/no)

Applying this patch:
[PATCH] rfkill: fix rfkill_set_states() to set the hw state
sent by Alan Jenkins does not help this issue either...

Any  suggestions how to fix the rfkill ?
