I added the above info to the bugzilla, but there is no card1, the nvidia
sound just completely disappears.

I think all the other info is already buried in some of the log files
I added to the bugzilla.

However, the most interesting fact so far is that if I rename the
snd-usb-audio.ko kernel module so it can't be loaded, I can boot with
the webcam plugged in, and everything (except, of course, the USB
microphone) works fine.
