Kernel Headers for 2.6.11

[Aethon <aethon@gmail.com>]

Hi,

I'm trying to upgrade my kernel from 2.6.8-11-amd64-k8 to
2.6.11-amd64-k8. The package installs fine and boots up ok, and even
recognizes my sound card (which the 2.6.8 kernel does not, hence the
reason I'm upgrading). The problem is when I try to install the nvidia
module. I've installed the module for 2.6.8 using module-assistant with
no problem. When I went to do this on 2.6.11 I get a problem running
"module-assistant prepare". It complains that it cannot find the
package kernel-headers-2.6.11-9-amd64-k8. I've search around for the
package on packages.debian.org and can't seem to locate it. So where
can I find this package or something else to resolve this dependancy?

If it is relevant, my /etc/apt/sources.list has
deb http://debian.csail.mit.edu/debian-amd64/debian/ testing main contrib non-free
deb http://debian.csail.mit.edu/debian-amd64/debian/ unstable main contrib non-free

I'm running testing with the occasional package from unstable.

Thanks,

Aethon
