Oh, did not notice it was included in mainline already.
I applied the attached patch. Insmod now gives:

insmod: error inserting 'samsung-laptop.ko': -1 Invalid parameters

and the logs contain the following:

kernel: samsung_laptop: found laptop model 'N220'
kernel: This computer does not support SABI

What is this SABI and SECLINUX thing about? Do you have a link to any more 
information? Is it possible that the N220 does not have this?
The N220 uses a Pine Train platform (featuring N450 with 64bit support), so I 
installed x86_64 to the device.

I would be glad to test whatever you give me.

Regards,
Chris
