Never anymore.

I would want use a specific tag or commit (i.e. git reset --hard vX.Y) 
moreover I would want decide when update and switch to a different 
(updated) tag or commit.

Personally I don't use tarballs at all anymore: I'll download the 
project's repo and build from it. I'm very happy if Aboriginal let me 
work in this way.

For example (sorry in git-ish):

git clone aboriginal
cd aboriginal/ && ls
build.sh config cross-compiler.sh .. (these should works with any 
version and doesn't care if gcc is 4.2.2 or 4.7.1)
ls package/linux (<- this is a submodule)
git submodule init
git submodule update
cd package/linux
git reset --hard origin (reset to the Linus' HEAD)
(don't change anything other aka let's use Rob's default versions)
./build i686-virtio

Why I bother with this crazy request? Because In this way I can handle 
multi-level changes in a very simple way. So if I want add a feature 
which needs to change/patch kernel, libc and application I could treat 
this like a single atomic commit.

Ciao,
Alessio
