FWIW, we ship SeaBIOS source directly in our release tarballs.  There's nothing 
indirect about it.

Fedora could have a seabios-qemu RPM that was built from the qemu SRPM.  Since 
it ultimately is going to live in /usr/share/qemu, that seems like a nicer thing 
to do AFAICT.

You could have an alternatives mechanism if people really wanted to use upstream
