Yepp, and I also had tried changing it to '2' and also snd_pcsp instead 
of snd-pcsp but that didn't work either.

Still snd_pcsp is the winner:
#######################################
cat /proc/asound/modules
 0 snd_pcsp
 1 snd_via82xx
 2 snd_mpu401
#######################################

As I understand, the sound devices are assigned by udev nowadays (at 
least that's what claims alsaconf). Maybe something should be 
blacklisted there? But how, and what?

Btw.: I have a message concerning pcsp during boot:

#######################################
dmesg | grep pcsp
[   12.290322] Error: Driver 'pcspkr' is already registered, aborting...
#######################################


Cheerz,
