There is a /etc/modules.conf which is the kernel modules configuration file where you can create aliases, override module path etc. if you want (read the manual page for modules.conf, example http://linux.about.com/od/commands/l/blcmdl5_modules.htm). By the way, by manually loading something from different location but the default one don't you already know the location of that file :)
