kernel module: netlink error

Hello everybody,

I'm trying to develop a kernel module for Nokia 770 TabletPC, with the
kernel 2.6.16.27-omap1. I use scratchbox with ARMEL to generate code for
the Nokia 770.

To communicate to kernel space I use netlink functions. To initialize I
use netlink_kernel_create. 

But when I run the module I get this error:

failed to create netlink socket.

This message is showed when the returned value of the netlink called is
NULL. But I don't know why this happens.

Could you help me, please?

Thanks in advance,
    Juan Antonio
