I remember running into this as well.

Again, I would wipe out everything in /lib/modules/`uname -r`/extra and /lib/modules/`uname -r`/kernel/drivers/isdn/hardware/mISDN, reinstall from source then ldconfig and depmod -a. Make sure you don't have the old drivers loaded onto the stack either by doing a lsmod/rmmod.
