I asked Tom Callaway, who heads up all the legal/licensing issues for
Fedora.  He said essentially "it won't be in Fedora" on just the basis
of MODULE_LICENSE.  I can run it past Red Hat lawyers too.  It's just
not clear with only MODULE_LICENSE, and not clear pretty much means
Don't Touch until it becomes clear.
