Don't have hard data. Just 6 years experience in kicking RHL and Fedora
into working for SPARC.

What I've learned:

Most open source apps build fine on SPARC. Those that do not are either:

- endian unclean
- missing sparc configure options
- miscompile on sparc64
- glibc/gcc/kernel/openssl (only broken on sparc)
- tools need to be made aware of sparc specifics
- irrelevant on sparc

I _never_ in 6 years uncovered a generic bug while working on sparc. The
"primary" arches in RHL and Fedora always covered those bases (even
before ppc was in the mix again).
