It would seem that I do not have a "modules.conf in /ect/. I have opened 
konqueror in super user mode and done a search starting from / and the only 
matching file I can find is in 
file:///usr/share/doc/kernel-doc-2.6.18/Documentation/video4linux/bttv/Modules.conf.
I do have a modeprob.conf in /ect and it does have some sound entries in it. I 
can post the contents if needed.
