Binary package hint: nvidia-173

nvidia-173 fails to build kernel module with kernels 2.6.35 and 2.6.35

With my recently updated Ubuntu 10.10, the nvidia-173 package fails to
build the kernel module for the latest 2.6.35-24-generic kernel, and
also for the newer 2.6.36-020636-generic. It does, however, build it for
the older 2.6.32-24-generic kernel.

It seems to fail because: "the kernel source for this kernel does not
seem to be installed."

Here is what it does when it works (w/ 2.6.32):

With the failed 2.6.35/2.6.36 attempts, this is the output for "find /var/lib/dkms/nvidia-173/": (it should be full of source files, etc. It's not.)
/var/lib/dkms/nvidia-173/
/var/lib/dkms/nvidia-173/173.14.28
/var/lib/dkms/nvidia-173/173.14.28/build
/var/lib/dkms/nvidia-173/173.14.28/source


So, why is the "kernel source" missing?

And, on a somewhat related note, why does each
installation/reinstallation attempt of nvidia-173 "remove all DKMS
Modules"? This is very annoying, since it doesn't allow us to boot into
different kernels, without having to manually reinstall nvidia-173 each
time.
