As promised in my blog yesterday, I am writing this as a QD (quick and dirty, but more quick than dirty) writeup of what to do - and one thing NOT to do.
Updated with links for debian-7.2
A quick explanation of my hardware: Power5 (model P505, 1 CPU, 20G internal RAM, 2 internal disks (70G) and an NAS that presents iSCSI disks to the VIOS (IVM)). So, fairly basic stuff.
FYI: In the past Linux (2006) would only install when it was presented a whole disk. As I only had two disks this was too expensive in terms of resources (I was installing AIX on 4B logical partitions exported via vSCSI as hdisk0). And I waited for Debian to support basically anything I would throw at the partition as a disk - and this week all the pieces seem to fit! EXTRA: Also tested on a friends Power7 (P710) using a logical partion exported as hdisk0!
Step 1: Get the iso image from debian.
mamfelt@x121:[/home/michael] wget http://cdimage.debian.org/debian-cd/current/powerpc/iso-dvd/debian-7.2.0-powerpc-DVD-1.iso /data/prj/debian
mamfelt@x121:[/home/michael] wget http://cdimage.debian.org/debian-cd/7.1.0/powerpc/iso-cd/debian-7.2.0-powerpc-netinst.iso /data/prj/debian
Step 2: Create - if not already present - a Virtual Repository on the VIOS
# as padmin, with /data/prj/debian already mounted (wget is not on VIOS image)
padmin@vios mkrep -sp rootvg -size 12G
Step 3: copy the downloaded .iso files into the repository so that they can be loaded onto a virtual optical drive
padmin@vios mkvopt -name debian_DVD1_710 -file /data/prj/debian-7.1.0-powerpc-DVD-1.iso -ro
padmin@vios mkvopt -name debian_netinst_710 -file /data/prj/debian-7.1.0-powerpc-netinst.iso -ro
padmin@vios lsrep

Name File Size Optical Access
debian_DVD1_710 3815 None ro
debian_netinst_710 258 None ro
Step 4: create a new parition without a disk
# done using IVM/HMC, no CLI commands to show here
Step 5: assign disk, create optical drive, and load optical drive
padmin@vios mkvdev -vdev hdiskX -vadapter vhostZ -dev lpZ_hd0
padmin@vios mkvdev -fbo -vadapter vhostZ
padmin@vios lsmap -vadapter vhost6

debian_netinst_710 258 vtopt2 ro
Step 6: open console to new partition and activate partition
# using IVM, assuming parition id #6
padmin@vios mkvt -id 6
# using HMC - go through menu to partition
michael@hmc vtmenu
# use HMC/IVM to activate partition
Step 7: using console interface boot from DVD, at boot prompt enter "expert"
# I expect you to be able to go through SMS menus to select boot device. I will have a film for this later.
Step 8: proceed with installation, using default answers until you are shown
VERY IMPORTANT - READ CAREFULLY !

¦ ¦
¦ The primary function of an initrd is to allow the kernel to mount the ¦
¦ root file system. It therefore needs to contain all drivers and ¦
¦ supporting programs required to do that. ¦
¦ ¦
¦ A generic initrd is much larger than a targeted one and may even be ¦
¦ so large that some boot loaders are unable to load it but has the ¦
¦ advantage that it can be used to boot the target system on almost any ¦
¦ hardware. With the smaller targeted initrd there is a very small ¦
¦ chance that not all needed drivers are included. ¦
¦ ¦
¦ Drivers to include in the initrd: ¦
¦ ¦
¦ generic: include all available drivers ¦
¦ targeted: only include drivers needed for this system ¦

Be sure and choose "targeted" or you system will not boot. The initrd.img created for generic is too large for yaboot to load.
Step 9: proceed with defaults until system just before system reboots.
On VIOS unload the DVD
$ unloadopt -release -vtd vtopt2
Step 10: (re)Boot partition
In SMS menu you will probably need to establish the hdisk as bootable. As the system boots

If you have unloaded the DVD (Step 9) the system will boot from the hdisk after a short bit you will see:
