Looks like we are talking abount different things, Mike.
For splitting Mesa-package, we don't need to submit even single line of 
code into mainstream Mesa-sourcetree. All we need is to provide additional 
subpackages in the SPEC-file (look at attachment, where I provide a patch 
to the mesa.spec, used for building FC's mesa* rpm's).

All we need is to properly patch SPEC-file.

Who tolds about stable ABI-interface? I just suggest to split kernel into 
a number of packages and add "virtual" one, that install all of them. Of 
course, then someone will upgrade the kernel *all* installed packages 
would be upgraded.
