Subject: [PATCH] force key-release events for Samsung p560 and r560 laptops in 
	atkbd.c

Hi all,
certain FN keys on the Samsung P560 and R560 laptops do not produce
"unknown key pressed" events in dmesg. But if I use setkeycodes to
make them known the keyboard gets 'stuck'. These keys seem to not send
keyrelease events.

Attached is a patch for the SAMSUNG P560 laptop, the DMI match just
needs to be modified to work for the R560 model as well. keycodes are
afaik (a colleague has the R560) the same for both. I modified an
existing patch for the NC10 from bugzilla as it is basically the same
problem.

Thread:
http://bugzilla.kernel.org/show_bug.cgi?id=12021

and here is my bug report:
https://bugs.launchpad.net/ubuntu/+source/hal-info/+bug/338182

I hope someone can include this patch into newer releases of the kernel :)

with best regards,
Gordon Köfner
