Not to dispute your original claim of wanting to merge drivers earlier,
but a lot of the time, there are good reasons why the code doesn't get
merged.

As recently pointed out by the nouveau driver authors on the xorg
mailing list, they don't want the driver to be added to the main
kernel.org tree yet as they feel that their userspace/kernelspace
inteface is not complete and will change in the future.

We try to respect the authors of the code when not including them into
the kernel tree for situations like this :)

As for why Fedora added it, it might be because they can control both
sides of the boundry with matching packages much easier.

thanks,
