} If the hardware is 64-bit, why not just use straight sparc64?  What's
} different that makes that fail?

     One possible reason is smaller amounts of maximum memory on
older 64-bit machines.  Another reason that might concern some
people is that there is a known bug in Ultrasparc I processors when
running 64-bit apps that allow any program to crash the system.
The only way to prevent it is to not run 64-bit apps.  This is
reputedly the reason that Solaris only runs in 32-bit modes on
machines with an Ultrasparc I (NetBSD gives the admin the choice).
There could be other reasons, such as performance, etc., why an
admin would choose to run a 64-bit machine in what is essentially
a 32-bit mode.
