It appears the snd_usb_audio driver is a red herring, or at least a separate bug. I checked, and my dmesg log does indeed say "hda-intel: no codecs found!" on boot, which suggests that snd_hda_intel is loading and then failing to initialize properly, accounting for the usage count of 0.
If you're using 2.6.24-rc* kernel (or did 1.0.15 backports), make sure that you enabled all CONFIG_SND_HDA_CODEC_* configs. Some people tend to reduce options as much as possible although they are suggested as default=y.
