iATKOS v7 is running smooth on my msi u100, had only to install correct gma950 drivers, the provided drivers in the dvd didnt work out of the box, but everything else is running great, only thought is about updating to 10.5.8, i know the sleep problem and sleepenabler.kext can fix it but i don't wanna mess with it, 10.5.7 is great!
