Wouldn't it be good to call it N270? Atom is a series of CPUs from  
Intel that contain very different CPU features. More expensive ones  
for example do support VMX, while that first cheap one does not.

Yes, good point.  I'll rename it to something containing model number.

Cheers

Great :-). Are you also considering to work on an ICH-7 (or above)  
emulation?

I was considering adding parts of ICH and intel 945GSE (especially
grpahics) but I don't know yet what we'll end up needing most and how
much time I will have.  If you start on something related it would be
great to know.

As far as I see it, the only chance in getting Mac OS X guest support  
upstream is an ICH-7 or up implementation in qemu. So I was  
considering to start working on it. I haven't had the time to do so  
yet though, but it's one of the things on my todo list. I wanted to  
focus mostly on the IDE and LPC parts first. Takashi might help me out  
on an HDA emulation.
