[Paul Fitzmaurice]

I still have to confirm the audio when I get home, but using the dmesg 
program, I realized that the card was not autodetected propertly, and 
thus i had to define the card type in modules.conf.  after rebooting, 
 dmesg reported everyting properly.  Thanks for the info!  I will let 
you know if there are any other problems.
