Wctdm Kernel Module - Help Needed

I need some assistance with the wctdm kernel module. I know that the module must be run at boot to ensure that the card (and timing provided by the card) are available to Asterisk. If I do modprobe wctdm the module is loaded and Asterisk runs fine. The problem is that I must manualy type the command at each boot.

Any help someone can provide in getting the wctdm module to load at boot would be much appreciated. I have included my current modprobe.conf file below for reference.

My modprobe.conf file (CentOS 4.2)

alias eth0 e100
alias usb-controller uhci-hcd
options torisa base=0xd0000
alias char-major-196 torisa
install tor2 /sbin/modprobe --ignore-install tor2 && /sbin/ztcfg
install torisa /sbin/modprobe --ignore-install torisa && /sbin/ztcfg
install wcusb /sbin/modprobe --ignore-install wcusb && /sbin/ztcfg

install wcfxs /sbin/modprobe --ignore-install wcfxs && /sbin/ztcfg
