They have the same CPU model ID: # grep model /proc/cpuinfo model : 28 model name : Intel(R) Atom(TM) CPU N270 @ 1.60GHz # grep model /proc/cpuinfo model : 28 model name : Intel(R) Atom(TM) CPU 330 @ 1.60GHz I would like to propose to use the patch as it is. It's the best version we ever had. Carsten.
