Comments on: Discussion: What processor type (family) to select for Intel Atom in Linux kernel config http://blogs.koolwal.net/2009/11/13/what-processor-type-select-for-atom-processor/ It cannot get simpler than this!

The product sheets are here: http://ark.intel.com/ProductCollection.aspx?familyID=29035 The newer Atom D410 and D510 will support 64-bit instructions. So you could probably use the amd64 distro for those processos. My N270 shows up as dual-core on Debian 5.0(Squeeze). There probably won't be a special configuration for the Atom until GCC supports it. GCC 4.5 has options for the Intel Atom as listed on the Gentoo Linux wiki here: http://en.gentoo-wiki.com/wiki/Safe_Cflags/Intel#Atom_N270.2FN280 Maybe after gcc 4.5 ships there will be a new build option for the linux kernel?
