Last time I looked into this, it looked pretty difficult. The Ultras
are pretty radically different from the old Sparcs; they have the
64-bit address space, a different processor memory model (PSO, I think),
a fourth distinct MMU, a new memory bus architecture, and different 
devices. So a sun4u would be much more difficult than the Sun4m port,
especially if we wanted to keep one NetBSD/sparc instead of NetBSD/sparc-32
and NetBSD/sparc-64.

I believe that there was someone out there working on an Ultra port,
though I don't have my mail archive handy, so I can't check for sure.
Anyone know anything about this?
