Incorrect. Only ALSA drivers are loaded. The snd-pcm-oss module is
ALSA's OSS-compat module, it provides nothing but OSS compatibility
interfaces for apps that still need them.

$ modinfo snd-pcm-oss |grep description
description:    PCM OSS emulation for ALSA.


Its possible SLED10 still ships both ALSA and OSS though, I dunno.
