There are a few comments on how the Athlon differs from Intel because of the Alpha EV6, but not the more technical detail I was referring to.

The Linux option in bios is mentioned here.
Again, to get this "mode" you have to: a) Tell the BIOS to enable a "Linux" memory mode b) Have a Linux kernel (Linux/x86-64 I believe?) that supports it
Yes, that's a modification of the Linux/x86-64 kernel running on a "32- bit" Athlon, because it offers the extended, linear memory addressing and other memory management.

I think what Bryan here is talking about is called IOMMU by the kernel guys. _______________________________________________
Thanks - but both links again talk about a 32bit/4GB schema and don't talk at all about addressing >4GB without the need for paging - that was the statement Bryan made when posting.
