Question : How do you setup an automation script for modprobe?

I am trying to setup an automation script to load a wireless driver using the following command:
I put the following commands in /etc/modprobe.d/iwp3945

echo install ipw3945 /sbin/modprobe --ignore-install ipw3945 ; \
sleep 0.5 ; /sbin/ipw3945d --quiet >> /etc/modules.d/ipw3945
 echo remove ipw3945  /sbin/ipw3945d --kill ; \
/sbin/modprobe -r --ignore-remove ipw3945 >> /etc/modules.d/ipw3945

modprobe returns the following warning: ignoring bad line starting with echo. What is the correct syntax to get this script to work?

What else have you got in /etc/modprobe.d? It doesn't look to me like a directory where you should have scripts at all:

08:30:21$ ls -l /etc/modprobe.d  
total 12
-rw-r--r--  1 root root 6337 2007-05-19 16:11 blacklist
-rw-r--r--  1 root root  356 2007-05-18 07:16 isapnp
