Please confirm the presence or absence of the AllowEmptyInput option in 
your xorg.conf.

I tested yesterday and found that "AllowEmptyInput" "off" with dbus/hal 
running produced exactly the behavior you describe.

A FreeBSD major version upgrade with mixed old a new libraries can 
certainly cause problems, but the specific "laggy X11" problem is more 
likely due to that option.
