Same problem with X.org?

Looks like problem with Fn button. If I press and release it - there is no problem, but typically this button used with F1-F12 buttons, and then I press it few second until I press F1-F12 button too. Hold this button stick desktop while testing (when keymap -i is launched), but not gererate any scancode. This is expected behaviour for Fn button?
