[kde-freebsd] Sleep doesn't get initiated when the lid is closed

[Yuri]

I experience this issue: when kde4 (and laptop) have just been started, 
closing lid doesn't cause sleep, though kde settings ask for this.
But after I once cause sleep manually (acpiconf -s3 or pressing kde menu 
button), closing lid begins to work.

Is this am known issue?
