Did you rebuild the module with a 2.5.59 Makefile?

Yes, it's a 2.5.59 change according to the Changelog at

Module Sanity Check

This patch, based on Rusty's implementation,
adds a special section to vmlinux and all modules, which
contain the kernel version string, values of some
particularly important config options (SMP,preempt,proc
family) and the gcc version.

When inserting a module, the version string is checked against the
kernel version string and loading is rejected if they don't match.

The version string is actually added to the modules during the final
.ko generation, so that a changed version string does only cause relinking,
not recompilation, which is a major performance improvement over the old 2.4
way of doing things.
