Cool, now we got two ideapad drivers :p.

David just sent an rfkill driver to this list. Maybe you could merge your work ?

Thanks,

Could you point me where is the rfkill driver? Sorry I do not find it.

I will see what I can do.

Thanks.

Yes, I believe I can. will read patch from David and merge.

But I think i will not use \_SB_.SECN as major interface. I know there is
another command code of EC that can access HW switch status and shutdown
the interface.

Hm, interesting. What model (and BIOS version) are you testing with?

On my S10-3, (DMI BIOS version 2ACN23WW, date 03/12/2010), I get these
keys through the normal keyboard controller -- and we can tell the
brightness up/down apart, too.

http://git.kernel.org/?p=linux/hotplug/udev.git;a=commitdiff;h=9cd075e3

Do you see those keycodes too... and do they *stop* arriving through the
keyboard controller when you load your driver?
