Fixed(ish) Re: "nvidia: disagrees about version of symbol module_layout"

[Darxus at ChaosReigns.com]

I rebooted into the new kernel, and manually reran the dkms remove,
build and install:

sudo dkms remove -m nvidia -v 185.18.36 -k 2.6.31-12-generic
sudo dkms build -m nvidia -v 185.18.36 -k 2.6.31-12-generic
sudo dkms install -m nvidia -v 185.18.36 -k 2.6.31-12-generic

And the module loaded on reboot.

I suspect a dkms bug.  But since the version I was running, and the
version I was installing, matched out to the ABI... I really don't know
what the options are.

Is it likely that the symbol disagreement was evidence of exactly the sort
of binary incompatibility that ABI exists for?

I'm planning to try an ABI bump to version 2.6.31-12bfs1.41

This is for bug https://bugs.launchpad.net/ubuntu/+source/linux/+bug/424927
