yes.

No references to isdn in console.perms.d either but your suggestion was helpful 
nevertheless: I created 60-isdninfo.perms which has the appropriate definitions.

[root at ws2 fs]# cat /etc/security/console.perms.d/60-isdninfo.perms
<isdn>=/dev/isdninfo

<console>  0660 <isdn>       0660 root.dialout

This solves at least 3/4 of my problem as I can now access /dev/isdninfo as a 
local user.

Unfortunately, there are two problems left:
1. Obviously, this does not work when using a remote (X) login. Therefore a 
general solution with udev is still needed.
2. After logging in, the ownership on /dev/isdninfo is <user>.root instead of 
root.dialout. Why?

Thanks for your help so far :-) I don't think it is anything special for isdn, 
just general udev/permissions.
