Actually, it had to do with porting to the *Ultra*SPARC, which is pretty
well different when running in `native mode' than the rest of the SPARCs.

Just for starters, it has a 64-bit address bus, which in an instant makes
the programming challenges much like those for an Alpha.  (Solaris's
userland on the uSPARC is 32-bit, as it's the same userland that they use
for the other SPARC chips.  Therefore the processor runs in a sort of
"compatibility" mode.)

There was a discussion here about it some time ago.  Unfortunately, Sun
didn't care much for NetBSD thanks to FreeBSD's name recognition--and they
went about working on FreeBSD. What work they have done, I have no idea.  
However, I have strong suspicions that Eduardo will have NetBSD/sparc64 up
to snuff sooner than they'll get FreeBSD to production quality.
