Having done something very similar (except with 2.2.19pre17), I can tell
you that this is what happens. From the README in kernel-package
"...The old vmlinuz is moved to vmlinuz.old unconditionally. (Normally,
that is only done if the version of the new image differs from the old
one)."
Version here of course means package version. If both your old and new
2.4.17 both correspond to the package name kernel-image-2.4.17 then dpkg
considers these to be the same version.
"A note on boot loaders: the kernel-image install-scripts arrange to have
/vmlinuz and /vmlinuz.old point to the latest kernel image and the next
most recent one, respectively."
This README is worth perusing carefully, along with the other
documentation.

No, this would never happen. I assume you mean two symlinks pointing to
the same file?
