So Is 64 bit "user-space appls" the same as 64 bit kernal?

A clarification:
The 64bit kernel is installed if the hardware is 64bit, but by default, only
the 32bit kernel is enabled.
Some further info relating to 5.1 (you only said 5L):

Subject: [aix-l] How do I know is running 64bit
Hi Admins,
I installed AIX 5L on K260 (64bit box). I used bootinfo -K it showed 32.
I used getconf WORD_BIT also 32. I checked I installed the bos.64bit
fileset.
And the /etc/inittab has the load64bit:2:wait:/etc/methods/cfg64
>/dev/console 2>&1
How can it tell the OS is running 64bit?
Thanks,
Frank
