For what I need to test, I must use Solaris 8/9 on sparc64.  sparc32 is
not supported, as this is software which hooks kernel system calls.

So, why is sparc64 unusable, and what are the barriers to creating a
fully usable sparc64 emulator which can run Solaris 8/9 (sparc64)?  ie,
how far away is it and what resources are lacking?
