I believe it's because of genksyms during the build process, I had the
exact same problem a few weeks ago on a machine with old modutils. So
you should have cleaned everything and rebuilt from scratch after
installing your new modutils. BTW, the required modutils in
Documentation/Changes is still marked as 2.4.10, I hope it is still
enough.
