Comment 86 for bug 232170

No...I think backlight keys are bios handled...they work also in grub, kernel
booting, etc....
No popup.....

no xev output for Fn keys and no dmesg ....

because of this, we used acpid and some scripts to handle these events....I
don't remember what we used to read the keyevents.

So... the "lamer" scripts + acpid must continue to exist.... I don't think
someone will handle this events in kernel or with an official rpm.....
