/etc/isdn/capi.conf has nothing to do with asterisk/chan_capi or diva. You 
don't need this file.

Maybe there is a change in asterisk-1.6 I don't know, but is was necessary 
in the old days.

This means chan_capi cannot access /dev/capi20 or there is no controller 
added to capi core.

what permissions does /dev/capi20 has and has the user which is running 
asterisk the rw rights?

No, only capi if you don't use diva-optimized capi.

Your choice.

Any log messages? Anything about cards registeres to capi (if kernelcapi is 
used)?

Just check if your /dev/capi20 is correctly available for the asterisk user.
You can also use the user space tool 'capiinfo' to see what is available.
