Getting rid of a module

["S. C. Linnenbringer" <sl@eskimo.com>]

I'm trying to remove a sound module which I think is causing some problems. A 
simple rmmod won't work because it states that a device or resource is in 
use. Can I "kill" this resource or device somehow? It's the ac97_codec module 
which I believe is for my  disabled (!) on-board sound. I'm trying to set up 
my SoundBlaster and I believe this is causing some problems.

Thanks.
