Alright, I fixed my /dev/dsp mixup. I needed to have the alsa oss 
modules loading before btaudio. So simple! :P

Anyway, I've got an ATI TV Wonder (non VE!) and here's stuff:
First, /etc/modules.conf:

and for good measure, it'd be important to note that I needed to load 
the bttv module like so:
bttv tuner=17

Autodetection didn't work too well. :)
