add:

options snd-intel8x0 index=0
options snd-hdsp index=1

and you should be good to go. i believe the default order these days is
based on PCI bus device numbering. it could be something even more
random.

not sure about that. does rmmod claim that its in use? does lsmod show
which other modules are using it?
