Not sure when this started occurring, but after a recent upgrade my powerbook stopped loading 'snd-powermac' at boot time, causing later scripts that depend on the mixer to fail.
I also see this problem. I am using an iBook. After the system boots I have to manually modprobe snd-pcm-oss and snd-pcm-mixer. This was not necessary before. However, like Jesse, I do not know at what point this problem surfaced. I am tracking Raw Hide.
Just FYI, this still occurs using the 2.6.15-1.1898_FC5 kernel.
still no sound after system boot - powermac g5 2.6.15-1.1948_FC5 udev-084-1.ppc64 udev-084-1.1.ppc # esd ALSA lib confmisc.c:672:(snd_func_card_driver) cannot find card '0' ALSA lib conf.c:3492:(_snd_config_evaluate) function snd_func_card_driver returned error: No such device ALSA lib confmisc.c:392:(snd_func_concat) error evaluating strings ALSA lib conf.c:3492:(_snd_config_evaluate) function snd_func_concat returned error: No such device ALSA lib confmisc.c:1072:(snd_func_refer) error evaluating name ALSA lib conf.c:3492:(_snd_config_evaluate) function snd_func_refer returned error: No such device ALSA lib conf.c:3961:(snd_config_expand) Evaluate error: No such device ALSA lib pcm.c:2099:(snd_pcm_open_noupdate) Unknown PCM default # modprobe snd_powermac # esd "duedeldidei"
Having the same exact problem here on my powerbook. Attaching scsound.log

probably sound modules should be loaded in /etc/sysconfig/modules/udev-stw.modules? currently, it loads only #!/bin/sh for i in nvram floppy parport_pc parport lp;do modprobe $i >/dev/null 2>&1 done
