Nah, I'm runnin' a desktop. I just gave up with the integrated graphics and got a GF8600 512MB. Work with full EVERYTHING outta the box (NVInject kexts at install)

I had similar troubles with my first attempt at an install though. The install GUI can take a looong time to boot sometimes so try giving it time first! Not sure what your specs are but try using the -v flag in Darwin (options when prompted) and see what it tells ya. That'll give you an idea of what it's stuck on. Then you can search the forums with what you find there. And make sure your install DVD was burned at the slowest speed possible on good media. I can tell you that the X1200 graphics on the laptops you've quoted are not full supported. You'll most definitely find the same prob that I found but there's no reason you shouldn't get it up n' running.

Keep at it and let me know how you go or if I can help anymore.... (or less!!!!)
