Which hardware exactly ? It this related to the N60 errata ?

well it seems to improve somewhat

as it doesn't do CPU frequency and voltage scaling,

what do you mean ? my frequency is now most often 2.10 GHz, and was 2.80 
GHz, so it does CPU frequency, doesn't it ?


so you shouldn't worry too much about this...
