You can't do it directly with the Fedora git setup, because Fedora git
just stores a 'sources' file which is a list of tarballs and their MD5
sums. The actual tarballs are stored in a lookaside cache somewhere
Nevertheless, several people have the same problem as you: at least to
my knowledge the kernel, libvirt and libguestfs.
These packages are now using git to manage patches, and then
generating the Fedora git setup as the last step.
For libguestfs I'm doing it manually. I have my own git repo which is
a clone of the upstream libguestfs git repo. In that git repo I have
the base stable version (eg. 1.4.3) plus cherry-picked patches on top
of that. I use 'git rebase' when a new stable version comes out, and
'git format-patch' to generate the actual patches which go into Fedora
git. At the moment I hand-edit the spec file to update the list of
patches, but eventually the plan would be to generate the list of
patches in the spec file too.
The result looks something like this:
(Sorry, but the git repo I'm using to manage the patches is not yet
libvirt is looking into writing tools to make this process more

libguestfs lets you edit virtual machines. Supports shell scripting,
bindings from many languages. http://et.redhat.com/~rjones/libguestfs/
