I've got nVidia nForce motherboard (Asus A7N266-VM) with Debian sid (testing) and 2.4.24 kernel. Nforce requires custom nVidia drivers for it's integrated devices, of which I would need only the network (nvnet -module). It compiles ok with vanilla kernel.

Nforce drivers can be found at

http://www.nvidia.com/object/linux_nfor ... -0269.html

After I patch 2.4.24 with grsec-1.9.13-2.4.24 the nvnet module gives the following errors while loading it insmod nvnet:

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.

Does anyone have solution for this?

have you also recompiled the nvidia drivers for this new kernel? also, can you check the symbols in your System.map to see what the difference is between what nvnet.o expects vs. what you actually got? you could also just turn off modversions.
