Ha ha, it really looks like it is overclocked. Celeron 220 is on FSB 133MHz and in this Asus it work with 166MHz hence the 1.5GHz speed. I see that this laptop use SiS chipset then it is very easy to overclock it with changing so called BSELs because it will not lock multiplier on 6 with core2 processors like Intel chipsets and since it's Celeron which don't have SpeedStep then it will not do that either. About incorporating microcode for Penryns it should be very easy because Asus use AMI bioses. Just find on internet lga771 to lga775 mod where everything is easy explained because in some cases they had to inject microcodes for lga771 xeons to have them work properly.
