i remember few weeks ago i configured a kernel that had the "Atom" option for the CPU type...
but now i'm compiling the latest kernel version 2.6.31.5, and that option is not there, the last cpu listed is Core2/Xeon...
Did i dream, or the Atom option has been removed?
Is there a patch to apply to add atom specific support?
(I plan to compile with GCC-4.5 that has -mtune=Atom support, and thus it would be perfect with a matching kernel..)
Distribution: Fedora on servers, Debian on PPC Mac, custom source-built for desktops

Try it without that option, it may autodetect it, and my Atom based acer aspire one running Fedora 11 just wants to know where it's kernel and initrd is and which partition to use as the root filesystem. UPDATE: I did not read your post well, I see what you are trying to do. Once again, try compiling without it.
As far as I know there was not any atom support in the kernel tho if you were using a source from a distribution they might have had some sort of custom patch that had been applied giving optimizations for the atom processor. From what I know of the processor is that it is just like a old Pentium processor except it has some of the more recent instruction sets.
I fin ally was able to Compile the 2.6.32rc5 kernel with CPU=Atom option, also using GCC 4.5 that has Atom optimizations (-march=atom -mtune=atom)
if i find time i'll do some quick benchmark..

"Atom CPU" option in the Kernel??
