I sure hope you can constrain keys to modules. One should be able to tell the kernel that the nVidia key can only sign the nVidia module, and to refuse anything else it signed...

Couldn't a compromised / hostile nVidia just creat a module that was called nvidia.ko, but did *bad thing*? Presumably one can't specify the allowed interfaces a module may use in advance.
Or am I misunderstanding you?

nVidia already signs its kernels for other OS, so what is the harm in asking them also sign the Linux version.
