Fedora Networking :: No Isdn Subsystem After Switching To 13?

I run in some trouble with my isdn card after switching from fedora 10 to fedora 13 (new installation, no upgrade) I made a default installation, after install and reboot/update I noticed that isdn4k-utils is not installed and I installed it manually. For setup of my isdn card I used system-config-network. But activate isdn (load kernel modules) fails, also with /etc/init.d/isdn start There is no isdn device: output cat /proc/net/dev

Code:

Inter-| Receive | Transmit
face |bytes packets errs drop fifo frame compressed multicast|bytes packets errs drop fifo colls carrier compressed
lo: 945856 2413 0 0 0 0 0 0 945856 2413 0 0 0 0 0 0
eth0:19685713 159678 0 0 0 0 0 0 87669282 139783 0 0 0 0 0 0

output lspci

Code:

05:00.0 Network controller: Elsa AG QuickStep 1000 (rev 01)

I suppose I forgot something at installation time. With fedora 10 everything works fine.
