I dug around and found the modinfo command...
$ sudo modinfo sound
filename: /lib/modules/2.6.26-1-686/kernel/sound/oss/sound.ko
author: Hannu Savolainen, et al.
description: OSS Sound subsystem
<snip>
vs.
$ sudo modinfo snd-pcm-oss
filename: /lib/modules/2.6.26-1-686/kernel/sound/acore/oss/snd-pcm-oss.ko
alias: sound-service-?-12
alias: sound-service-?-3
license: GPL
description: PCM OSS emulation for ALSA.
<snip>
This is from kernel 2.6.26-1-686 in Sid.
H.S., you could run modinfo on any sound-related
modules from lsmod to verify that they are not OSS
