Bug#789816: console-setup: Nokia N900 Keyboard Model is not fully supported by ckbcomp

[Sebastian Reichel <sre@debian.org>]

Package: console-setup
Version: 1.128
Severity: wishlist
Tags: patch

Hi,

The Nokia N900 keyboard model (nokiarx51) is not fully supported by ckbcomp.
It is generating a few "Unknown key type PC_FN_LEVEL2" lines and the cursor
keys are not mapped correctly for some keyboards variations.

The attached patch removes the warning and results in working arrow keys in
the Germany keyboard variation.
