I'll have to check this... it should work... Downloading the rpm was the
right choice.

Same for all versions. I try to keep my sanity by minimizing the number
of things I have to mantain :-)

This is part of the "building the kernel" process, ".config" is the
default name that the configure process will look for, maybe there is a
way to change the name but I don't know of any.

The changes are saved to the ".config" file. You cannot select a name (I
think). 

After that and if you want to recreate the binary rpms you have to copy
the .config file to the appropriately named configuration file in the
/usr/src/redhat/SOURCES directory (not back to the configs directory
because that will be erased and repopulated with what is in the SOURCES
directory when you start rebuilding the kernel). Also, you should
probably select the i686 configuration file, you could select athlon but
I have never tried it, I just distribute a i686 kernel only (to avoid
building more kernels than necessary :-)
