X not working since yesterday's update

["Horst H. von Brand" <vonbrand inf utfsm cl>]

Since yesterday, Gnome (and XFCE4 beta, and WindowMaker) start fine, I can
move through the graphical menus fine, but not start any programs that way.

Starting from another vty:

  DISPLAY=:0 xterm

gives a normal xterm, but I can't type anything into it, no reaction to
mouse, ...

I think this is due to xorg-x11-server-Xorg-1.1.1-43.fc6 (or something in
that bunch), but I have no earlier version I could try.
