This seems like unneeded voodoo.

You have already demonstrated that ztcfg ran perfectly well after system
boot with no startup.

Conisder the following startup sequence:

	TMOUT=10 # timeout for udev to populate /dev/zap
  	# maybe it does nothing, as the module is already loaded by 
	# hotplug/udev ?
	modprobe wcte11xp 

  	# wait for /dev/zap/ctl:
	while [ ! -c /dev/zap/ctl ] ; do
		sleep 1
		TMOUT=`expr $TMOUT - 1`
		if [ $TMOUT -eq 0 ] ; then
			echo "Error: missing /dev/zap/ctl. udev problem?"
			exit 1
		fi
	done
	/sbin/ztcfg

Basically the same as in in the zaptel init.d script but with lots of 
junk removed.

Also, be sure to remove the lines in the modprobe configuration that run 
ztcfg on module startup. Otherwise you defeat the purpose of the above
loop.
