RPM to GIT tree integration?

Hi,

This is a wild shot in the dark but I thought I'd better ask in case some one has. Has anyone created a script/tool that can take a src RPM and apply it's patches (in sequence) to an existing GIT tree?

In my case I just want a GIT tree for a vendor kernel. I could just prep an SRC RPM and commit the thing wholesale into GIT and start hacking but then I'd loose all the history benefits.
