"nvidia: disagrees about version of symbol module_layout"

[Darxus at ChaosReigns.com]

I patched the kernel package, built it via debuild, purged the packages
with a matching version, verified that /lib/modules/2.6.31-12-generic
was completely removed, installed my new packages, watched dkms do it's
thing with the nvidia module, rebooted, and got the error in the subject in
dmesg.

How do I fix it?

Packages I installed:
linux-doc_2.6.31-12.41bfs1_all.deb
linux-headers-2.6.31-12_2.6.31-12.41bfs1_all.deb
linux-headers-2.6.31-12-generic_2.6.31-12.41bfs1_i386.deb
linux-image-2.6.31-12-generic_2.6.31-12.41bfs1_i386.deb
linux-libc-dev_2.6.31-12.41bfs1_i386.deb

Verification that I actually booted it:
$ uname -a
Linux dancer 2.6.31-12-generic #41bfs1 SMP Thu Oct 8 20:43:26 EDT 2009 i686
GNU/Linux

dkms stuff from package installation:
run-parts: executing /etc/kernel/postinst.d/dkms
 * Running DKMS auto installation service for kernel 2.6.31-12-generic
 *  nvidia (185.18.36)...
nvidia (185.18.36): Installing module.
