It _is_ 64 bit when it reads "UltraSPARC". I have a Ultra 5 with 300 MHz
US IIi and belive me, it runs a 64 bit NetBSD kernel. Maybe you are
confused by the fact that Solaris instales 32 bit kernels by default on
some UltraSPARC systems. AFAIK all US I systems. The US I CPU has a bug
that can be used to stall the CPU and crash the machine when a 64 bit
Kernel is running. The bug can't happen when a 32 bit kernel is runing,
so Solaris "works around" this bug by instaling a 32 bit kernel.
