I just compiled and tested 2.1.90-pre3. This is what I configured in the sound section:
CONFIG_SOUND=m CONFIG_SB=m
everything else I set to n. All I want is /dev/audio and /dev/dsp. The relevent lines from my conf.modules are:
alias char-major-14 sb options sb io=0x220 irq=10 dma=1 dma16=6
So then I do a modprobe sb and everything works fine. Also, I didn't notice any switching of stereo channels (this is with an mp3 I just made from an audio cd, I even stuck the cd into my cdplayer and it sounded just the same on it as through my sound blaster). I do an lsmod and this is what was returned:
Module Size Used by sb 22028 0 uart401 5516 0 [sb] sound 63244 0 [sb uart401]
Works well for me. The only difference I see is that I don't use module versioning.
And while I'm at it this oops occured when doing an "modprobe -r sb"
