Err, the Atom is a low end-chip. So no AMD64.
That is market segmentation for you.
Edit:Sorry, I was wrong. Only the Z and N don't have 64bit.
But with less than 4GB 64bit is toally pointless. You waste a lot of CPU cache for nothing. The system will be way slower.

Strictly speaking, don't the kernel tradeoffs begin above around 800MB? Bounce buffers and such? And don't forget all the extra registers that come with X86_64.
Personally, I think that 64 bit kernel with 32 bit user space, with individual 64 bit apps deployed strategically, is really optimum for many situations. The kernel has all the memory management advantages of 64 bit. But without the memory hit of 64 bit user space pointers, except where 64 bit can really help. As it *which* 64 bit apps to strategically deploy, if any... I'm not certain. And, of course, it depends upon the exact situation.

I create my USB boot things with unetbootin, but that one doesn't include the text installer option. On top of that, people are reporting the same problems with running systems - it's not just the live CD kernel that fcuks up. It's all a bit of an epic fail.
I'm kind of bummed. 64bit didn't work either.
