Hmmm...I changed this section of my modprobe.conf to the following and
success!

options snd cards_limit=8
alias snd-card-0 snd-intel8x0
alias snd-card-1 snd-usb-audio
options snd-intel8x0 index=0
options snd-usb-audio index=1

I can now access my sound devices correctly.  Seems kudzu or whatever is
doing the automatic h/w detection is barfing the wrong information into
modprobe.conf.

Moreover, is my configuration about 'correct' in that it is setup as it
should be?
