atkbd problem. Worked before some kernel update

[Ambrogio]

Hi all,

I'm running fedora core 6 with kernel 2.6.18-1.2869.fc6 #1 SMP Wed Dec
20 14:51:34 EST 2006 x86_64 x86_64 x86_64 GNU/Linux

I'm sure that until christmas my laptop (Acer 5000) worked well with
wireless and with the key to activate it.

Now I have log on messages like that
atkbd.c: Unknown key pressed (translated set 2, code 0xd6 on isa0060/serio0).
atkbd.c: Use 'setkeycodes e056 <keycode>' to make it known.
atkbd.c: Unknown key released (translated set 2, code 0xd6 on isa0060/serio0).
atkbd.c: Use 'setkeycodes e056 <keycode>' to make it known.

Do you know why it appens and how to return to old configuration?

Tnx
 Ambrogio
