 I can add my own two cents to this.
 
 If I run with Option AllowEmptyInput off, then the screen goes black,
 and I cannot regain any use of the console. Logging in over the
 network and killing the X server does not help. Upon reboot, I get the
 psychedelic screen reported by others. Sometimes the system hangs and
 I need to use the power button; other times it proceeds to reboot
 normally.
 
 If I run with Option AllowEmptyInput on, then I need to run hald,
 otherwise I have no keyboard or mouse input. With hald running, X
 events are often delayed. For example, running xev I see that clicking
 the mouse produces a ButtonPress event, but the corresponding
 ButtonRelease event is delayed until I move the mouse. I also often
 find that keyboard events are delayed until I move the mouse.
 
 I don't need to tell you how annoying this is ...  Apart from this,
 however, with hald running I see no further problems.

 (Yes, I have also run portupgrade -rf libxcb, and portupgrade -af too.)
