There was an endianess issue in the script which is fixed. Can we 
continue discussing my approach to patch the mac address at 
https://github.com/lede-project/source/pull/324? It is about the same 
topic and we already made some progress. The latest version of my patch 
is linked there as well.

It doesn't work yet completely, since there seams to be something in the 
caldata which triggers the replacement of parts of the mac address with 
random(?) values.
