Elimar,

Thanks for writing.

I've checked the udev database (/etc/udev/rules.d), and the rules  
only reference a NAME or possibly a SYMLINK. No post-install actions.  
I am pretty certain the post-install action was something triggered  
by modprobe and not udev.

And... it is. /etc/modprobe.d/alsa-base contains an explicit rule to  
run /usr/lib/alsa/modprobe-post-install. That file is part of alsa-base.

I promise you that taking the update made the package unusable. I  
guess I'm just lucky.

So does this bug get transfered to alsa-base? And why is my system  
the only one that stops working? (Maybe the install asked me if I  
should keep the old modprobe.d/alsa-base, and of course by default I  
would.)

Please let me know if you need any additional information.
