Permanently Unload Module

[Matt Peter <WetherMan@FLML.com>]

I'm encountering a problem with the ohci1394 module, which is causing 
system instability and general slow performance.  I do not need the 
module, nor am I particularly concerned with the problem it's causing, 
because after rmmod ohci1394 the system performs fine.

I've done some searching on the web, but I am unable to find a working 
method to automatically unload the ohci1394 module upon bootup.  Can 
anyone provide some insight into automatically unloading modules?
