Assuming the 2 320s we have at work are 320H (I'm not sure what the H
means) I believe (90% sure) they are POWER CPUs; basically slower
versions of the 340s which are definitely POWER. Unforetunately I
cannot find a way in AIX to display the processor information.

Don't know anything about Linux on these but from next year I'd be
able to give it a go as these machines are going out of routine.
