xorg and miltiple layouts bug

["Bogdan B. Rudas" <rudas@jbaw.iba.by>]

Hi!
I use xorg from http://people.debian.org/~nobse/xorg-x11/
I notice, that 3 layouts at same time does not works.
I do:
setxkbmap -option
setxkbmap -layout "us,ru,by"
setxkbmap -option "grp:alt_shift_toggle"

layouts "us,ru" "us,ru(winkeys)" "us,by" works well.
In Xfree from sarge I use layout "us,by(winkeys),ru(winkeys)

I try to write layout defenition in xorg.conf. I got no error message in 
log, it looks fine:
(**) Generic Keyboard: Core Keyboard
(**) Option "Protocol" "standard"
(**) Generic Keyboard: Protocol: standard
(**) Option "AutoRepeat" "500 30"
(**) Option "XkbRules" "xfree86"
