Right, it's saa7134-alsa that takes the index parameter, but when you 
load saa7134 with the "oss=1,1" parameter, it automatically loads
the saa7134-oss module -- and it does so by mistakenly passing it the 
"index" parameter, and consequently it fails. In other words, the OSS 
module functions as a default when "oss=1," is specified, so I never get 
a chance to issue "modprobe saa7134-oss dsp_nr=4,5,6,7 mixer_nr=4,5,6,7".
