POWER3 is a 64 bit CPU and is the processor used on various machines such
as the 260, 270, B80, etc.

DCE 3.2 doesn't support 64 bit kernels as far as I am aware (according to
latest docs available at the DCE 3.2 web site).

Is it possible to run the POWER3 machines with a 32 bit kernel, or do they
absolutely require the 64 bit kernel to boot and run?

nope, just relink your /unix file to unix_mp instead of unix_64,
bosboot -a then reboot.

i.e

ln -fs /usr/lib/boot/unix_mp /usr/lib/boot/unix
ln -fs /usr/lib/boot/unix_mp /unix
bosboot -ad /dev/ipldevice
shutdown -Fr
