I haven Aspire One A150, currently running Snow Leopard 10.6.1. It is pretty much vanilla, apart from the VoodooHDA, IOSHDC etc. The problem I have is that with Leopard, I could run an external monitor no problem at all. Since upgrading (and installing the SnowGMA kexts), everytime I connect an external monitor my laptop reboots. If I boot with it connected, it boots to twin grey screens. Any one have any ideas? Do I need natit.kext?
