I'm interested to do like you did:
> 'And a separate sound card: one for non-JACK ALSA apps, one for JACK apps.'

is there a howto available howto setup 2 soundcards, one for jack, one for 
non-jack ?

- how do I address 'jackd' to the soundcard I want?

- can I use alsaconf to configure 2 soundcards, or do I have to edit
  something like modules.conf manually?

thanks for some hints and your time....
