I have a fujitsu 8420. I can install kalyway but no drivers work. I need drivers for my graphics card(intel gma x4500). So, if new macbooks come out with the same graphics card will I be able to get the driver and use it without problems?

New macbooks will be using nvidia graphics so probably not.

And you know this HOW exactly?

We should all find out on Tuesday...but I don't see lowend MacBooks nor the MacBook air going to discrete video.

nVidia can easily make a non-discrete chipset

it is said that it would use nvidia 9600 on pro.
but seems that is a g92 core one?

What does "it is said" mean? Anyhow, all we can do is guess...but I'm thinking on the rumored $800 model we will see integrated video. Find out Tuesday

but if it does use x4500 will they make drivers for it?

If it uses the 4500 for video, then of course they will have to make drivers for it. Whether or not they would require hacking and/or work on PC's 4500 would remain to be seen. Historically it has worked with some work (GMA950) or out of the box (some GMA X3100)

and the verdict is in....and no GMA X4500. oh well

Well the $1299 and $1599 MacBooks use the nVidia 9400M chipset, but maybe the $999 one uses x4500HD


edit:
Haha.. crap, the $999 one is actually the now-old MacBook. My mistake..

the 999 is the current model...X3100 IIRC
