Nightshade: yes they are overclocked but the 32mb version of the GeForce440 Go is actually faster than the 64mb version of the same chipset. It has to do with how the memory is handled.
Schizophonic: Try using the new version of the Det drivers. You should get a gain in performance over the previous ones (at least 5%). There are a number of tweaks out there for laptops. Try doing a search at Guru3d.com, HardOCP and other comparable sites. I just tested my system again, this time with the laptop chilled

and got almost 6000 points on 3DMark2001se. I can only assume that the people on MadOnion use a similiar method, as getting high scores like what they have probably come from extreme tweaking and cooling. Good luck
