natty doesn't recognize touchpad toggle key on Dell Inspiron 1464

[Funnnny]

Binary package hint: hotkeys

I have a Dell Inspiron 1464 laptop, it has a touchpad toggle key that work fine in 10.10.
I've just upgraded to 11.04 and the button stop working.
running dmesg get me to this
[ 3546.192493] atkbd serio0: Use 'setkeycodes e01e <keycode>' to make it known.
[ 3546.250041] atkbd serio0: Unknown key released (translated set 2, code 0x9e on isa0060/serio0).

[ 3546.406235] atkbd serio0: Use 'setkeycodes e01e <keycode>' to make it known.
So I think in some reasons the button wasn't set any keycode by natty.
