snd_emu10k1, alsa, and /dev/dsp dissappearing

I have a SoundBlaster Live! (snd_emu10k1) on my fresh Slackware install, upgraded to kernel 2.6.12. I can get alsaconf to detect the card, but the necessary devices aren't there. I can mknod /dev/dsp, /dev/mixer, /dev/sequencer, and /dev/midi. This will allow rexima to work to increase the volume and mpg321 will play sound. However, mpg321 throws up a ton of alsa errors in the process.
gort32@aerandir:~$ mpg321 /tmp/Welcome_to_the_Internet_Helpdesk.mp3

xmms gives a scarier error:

alsactl store gives the error:

Does anyone have any additional ideas to try?

Are you using udev by any chance? Maybe you need to make sure you appropriately set up the devices either by adding a script to /etc/udev/scripts or copying the devices as created by the snddevices script in the alsa sources to /etc/udev/devices/ so they can be seen upon boot... I haven't seen this myself, seems quite strange.
