You're having the same problem I had when I upgraded to Fedora Core 3
(with the 2.6 kernel).  I have a TDM400P with 3 FXS modules.  I had to
add some sleep statements between modules loads for some reason.  Try it
out.  This is my edited init script:

[ clipped from /etc/rc.d/init.d/zaptel ]

MODULES="wcfxo wctdm"

RMODULES="wctdm wcfxo"

if [ "${DEBUG}" = "yes" ]; then
        ARGS="debug=1"
fi

# See how we were called.
case "$1" in
  start)
        # Load drivers
        rmmod wcusb >& /dev/null
        rmmod wcfxsusb >& /dev/null
        rmmod audio >& /dev/null
        action "Loading zaptel framework: " modprobe zaptel
        sleep 1
        echo "Loading zaptel hardware modules: "
        for x in $MODULES; do
                echo -n "     $x "
                modprobe ${x} >& /dev/null
                echo " - Sleep 1"
                sleep 1
        done
        echo "     Sleep 3"
        sleep 3
        echo
        action "     Running ztcfg: " /sbin/ztcfg
        RETVAL=$?

        [ $RETVAL -eq 0 ] && touch /var/lock/subsys/zaptel

        ;;
  stop)

[ end clip ]
