Just one last point in case anyone is interested... The file does not have to be called /etc/modprobe.d/local It can be anything you like... such as /etc/modprobe.d/psychopath if you like. It seems that modprobe functions in such a manner as to scan and process all files in the /etc/modprobe.d/ directory. This is useful for keeping various groups of stuff seperate, as is apparent in the default installation. ;-|
