The answer appears to be to add an empty LISTEN statement to 
/usr/local/lib/X11/xdm/Xaccess. The xdm package issues a IPV6 DHCP request. 
While the xdm man page suggests this is not needed:

        To disable listening for XDMCP connections altogther, a line of  LISTEN
        with  no addresses may be specified, or the previously supported method
        of setting DisplayManager.requestPort to 0 may be used.

This seems not to be the case as adding this line gets rid of the long delay and 
suppresses the IPV6 DHCP request. The DisplayManager.requestPort is set to 0 in 
the default configuration. This solves the long start (I am pretty sure). Thank 
you for your suggestions that pushed me to find this.

I am also pretty sure my hardware just does not work with hal and dbus.
