Or that newer hardware is unsupported? sparc64 supports sun4u which is most boxes, Fujitsu Sparc64 boxes also work quite well. The only thing really missing is sun4v and a few drivers here and there. OpenBSD has support for almost all of the newer Sun/Oracle boxes, which shouldn't bee too hard to port over. http://www.openbsd.org/sparc64.html Because of the lack of sun4v support i have moved over to a custom illumos distro, but one of the things im working on there is to replace gcc with clang/llvm. If it means saving the sparc64 port i will gladly move some of my work over to freebsd.
