Hello,

pressing some keys on laptops could cause some side effects.

Example scenario 1:

Laptop has Fn key for enabling/disabling WIFI and when that key 
is pressed BIOS is doing two things:

1) Switch hard rfkill state of WIFI
2) Report that Fn key was pressed to kernel
   (either via i8042 bus or via ACPI/WMI)
We should not really report that as a "key" to userspace. We might
want to report that rfkill state changed....
