Steps to Reproduce:
1. # alsaconf
/etc/modules.conf:
# --- BEGIN: Generated by ALSACONF, do not edit. ---
# --- ALSACONF verion 1.0.5 ---
alias char-major-116 snd
alias char-major-14 soundcore
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
alias snd-card-0 snd-intel8x0
alias sound-slot-0 snd-intel8x0
# --- END: Generated by ALSACONF, do not edit. ---

2. # alsamixer
alsamixer: function snd_ctl_open failed for default: No such file or directory

3. #service hotplug restart
...
Sep 29 11:18:16 titan hal.hotplug[13493]: DEVPATH is not set (subsystem pci)
Sep 29 11:18:17 titan pci.agent[13494]: missing kernel or user mode driver 
snd-intel8x0
Sep 29 11:18:17 titan hal.hotplug[13533]: DEVPATH is not set (subsystem pci)

4. lsmod
Nothing related to audio modules

5. # modprobe snd-intel8x0
modprobe: Too deep recursion in module dependencies!
modprobe: Circular dependency?
Aborted

Actual Results:  
No alsa module loaded (no device showed by KMix)

Expected Results:  
Correct audio subsystem (alsa audio modules correctly loaded, a sound should be
heard from dynamics)
