I think the subject would better read: "What is best way to represent multimodule CVS repository in Git?"

I think that such setup would be best managed by creating Git repository for each piece, and "integration" repositories, one for apps people, and one for firmware people, using submodule support in Git.

Tagging entire release would be tagging in "integration" repository, the one using submodules.
