OK, so 'cd' is scancode for KEY_RIGHT and 'cf' is scancode for
KEY_END, and it seems that implementation of FN handling is very naive
as it emits "release" keycodes for the state FN is currently in, not
the state it was when key was pressed.

Ideally Dell would fix that. Mario, any chance of that?

I'm just wondering whether this is still something that could be fixed
or worked around in the input driver,

Well, obviously I'd rather fix the bug at its root rather than piling
workarounds in the driver.

since the bug obviously doesn't
show up in neither in the linux console nor in Windows.

So where does it not work in Linux? Because keyboard driver in console
and elsewhere is the same. Maybe it is not noticeable when in text
console?

In Windows the bug might be masked if they use hardware autorepeat for
PS/2 keyboards. I don't know if they do or not.

Thanks.
