Simple keep different filenames for both the kernels... dont overwrite the existing kernel.... as the version of both of them would be same....
You can do one thing to avoid this.... always maintain a symbolic link called vmlinuz that points to the kernel that you want to use... and add the name of this symbolic link to the lilo or grum config files.
