This is direct from IBM in an email I received:

COMMAND: bootinfo -K

Reports whether the system is running a 32-bit or
64-bit KERNEL.

- AIX4.3 has only a 32-bit kernel

- AIX5.1 has both 32-bit and 64-bit kernels. Only
one [1] can be active on a system [or within a
LPAR] at a time.

COMMAND: bootinfo -y:

Reports whether the CPU is 32-bit or 64-bit.

COMMAND: oslevel

Reports the AIX version.

COMMAND: smit load64bit

Used to determine/set the USER-SPACE runtime
environment is 32-bit or 64-bit

Note 1: Requires AIX4.3 or later.

Note 2: Invalid - not possible to run 64-bit
kernel on 32-bit hardware.

Note 3: Requires AIX5.1 or later.

Note 4: 64-bit user-space appls:

bos.64bit fileset must be installed and
activated using the command "smit load64bit"

AIX4.3 64-bit appls not supported on AIX5.1.
They must be recompiled.

Note 5: The AIX5.1 32-bit kernel is default.

The AIX5.1 64-bit kernel is optional.

The AIX5.1 64-bit kernel is installed on
64-bit hrdw by default, but is inactive.

The AIX5.1 64-bit kernel can be activated at
install-time or later using "smit load64bit"

Use "bootinfo -K" to determine which kernel
is running.

Use "lslpp -h bos.mp64" to determine if the
64-bit kernel is installed.
