Hi Diego, I also have a brant new Clevo W150HNM, but the Nvidia GPU switch off isn't working for me using Ubuntu 10.10 and kernel 2.6.35-28-generic 64bit (the default kernel).
May I ask you which kernel and ubuntu version you are using ? Moreover, I have stability problems: when the power isn't pluged in, the wired network card isn't stable, I can see link up/link down message every ten seconds or so in dmesg. Do you also have this issue ? Anyway, thank you for the fix for the suspend problem, I will try it this evening.
