modprobe -r module doesn't work on FC8

[Tom Poe <tompoe@xxxxxxxx>]

What command(s) to use to remove and install modules on FC8?  here's the 
quote I'm trying to understand:
"The webcam audio interface must be initialised before the video 
interface. Linux will by default initialise the video interface first, 
so you need to remove the uvcvideo.ko module from the /lib/modules 
subdirectory where it gets loaded automatically, and load it manually 
after plugging the webcam."
