The vpnclient is part of closed and open source and I am building
against my current and proper kernel tree. The build script is compiling
the sources and links those object files with a binary from cisco (the
closed part).
That is the relevant part from the driver_build.sh script:
#########snip###########

CFLAGS="-O2 -DCNI_LINUX_INTERFACE -D__KERNEL__ -DMODULE
-D_LOOSE_KERNEL_NAMES -DHAVE_CONFIG_H"
case `uname -r` in
2.[56].*)
make "KERNEL_SOURCES=${KSRCDIR}"
;;

We I try to load the module I get the following mesages:

Hint: You are trying to load a module without a GPL compatible license
and it has unresolved symbols. Contact the module supplier for
assistance, only they can help you.
As i mentioned before, I do have a working module for several month. But
with my current Owl release, I am not able to set it up again.
Greetings
