The solution for this, and for any case where multiple flavours apply to the same machine, or if multiple kernel versions are available, would be to have the kernel package set a debconf variable with all the choices, and use debconf to chose the actually booting kernel, and then set the symlinks accordyingly. This can be done in a way similar to how the powerpc mkvmlinuz does its debconf magic, by putting adequate files under /etc/kernel/post-inst.d, which would then be used to setup the bootloader, instead of the current way.
