asus wireless LED does not toggle in karmic

[Donatas G.]

I have Asus A8F running Kubuntu Karmic Desktop i386

Karmic brought a lot of good changes - so far I had no problems with disabled 
wireless after sleep/hibernate. But there is one new problem: wireless LED 
stopped responding to Fn+Wireless or F2) keybinding. it does not toggle any 
more, although wireless does get turned off and on as usual.

How do I fix that? I cannot even turn it on/off manually (there used to  be a 
special file in /proc/acpi/... that I could echo a 0 or 1 to to change the 
status of LED, but the folder acpi/ no longer exists under /proc

Any ideas what file is used to control the LEDs in Karmic?
