Mouse stopped working in X

[J. W. Ballantine]

Hi,

Before the update of x11 on 4/21/2012, X was working fine, but now
when I startx, my usb and touchpad mouse are no longer found.  The 
mouse works in terminal mode, and hald and dbus are started in
/etc/rc.conf.

I rebuilt x11, but that had no effect, any ideas on what I might
do to get the mouse working again?

Here is the tail of the Xorg log.
