>Subject: [PATCH 02/02] Reworked input layer and add more keys
>Date:	Sat, 29 Nov 2008 18:48:58 -0200
>
>I made some changes in the work of Nicolas to support my asus M51Sn laptop.
>The higher event in my laptop is 153 so I think that will not be reasonable
>declare a 154 array hardcoding each key. And if another table be necessary
>the work will need to be redone.
>
>I fill a array with KEY_UNKNOWN and then after I put the codes that I found
>in my laptop. A new table can be added with other table contaning only the 
>differences for example.
>
>Some keys are overriding by firmware but I let it in the table to know which
>events are generated.
>
>So this patch change the implementation of the keymap focusing only in the
>keys that generate known events. And also makes it easier to support more
>than one keymap table.
>
>Add more keys events.
