Huh? My Debian system here has:

/boot/config-2.6.15-1-powerpc-smp

This corresponds to the config of the currently installed version and
revision ("2.6.15-8") of the "linux-image-2.6.15-1-powerpc-smp"
package. Since you can only have one version of a given package
installed at once, this poses no problems.
If I upgrade to a new one (say "2.6.15-9") that changes the config
slightly or adds a new distro patch, then that config and kernel
image would replace the currently installed one. If I use make-kpkg
to build and install a custom kernel tuned for "host":

make-kpkg [args] --append-to-version -zeus1-1-powerpc-smp --
revision 1 kernel_image

Now I get a package "linux-image-2.6.15-zeus1-1-powerpc-smp" version
"2.6.15-1", with:

/boot/config-2.6.15-zeus1-1-powerpc-smp

I see no potential for confusion or mismatch here.

Cheers,
