The only way I can see that working is if /usr/local/modules in 
kern.modules_path /before/ mount -a is executed by /etc/rc.d/mount. Which 
means there should be a line:
kern.module_path=/boot/kernel;/boot/modules;/usr/local/modules

in /etc/sysctl.conf on your machine.
Also, mount_ntfs-3g should be able to load the module dynamically.

What does ls -l /sbin/mount_ntfs-3g say?

Does /mnt/windows exist?
Anything interesting with `sh -x /usr/local/etc/rc.d/ntfsmount' ?

If I find some more time, I'll play around with it.
