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 reasonabledeclare a 154 array hardcoding each key. And if another table be necessarythe work will need to be redone. I fill a array with KEY_UNKNOWN and then after I put the codes that I foundin 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 whichevents are generated. So this patch change the implementation of the keymap focusing only in thekeys that generate known events. And also makes it easier to support morethan one keymap table.
