DLPAR fails on SLES9

I want to do DLPAR to add a virtual network interface (ibmveth) to one
of my LPARS, running Linux. I can't make it work. Note that adding a
physical network interface works without problems.

System: IBM OpenPower 720, managed by HMC
LPAR OS: SLES9, kernel 2.6.5-7.252-pseries64
Installed magical rpms from IBM:

I have tried both doing the DLPAR command via the HMC gui, and it's
cli, using this command: 

chhwres -r virtualio -m openpower1 -o a \
    -p vioserver --rsubtype eth -s 11 \
    -a "ieee_virtual_eth=1,port_vlan_id=1,is_trunk=1,\"addl_vlan_ids=690,691,692,693,694,695,696,697,698,699\"" \
    -w 5 -d 5 

When ran by the hmc cli, I only get this dumb error:

HSCL294C DLPAR ADD Virtual I/O resources failed: HMC adding Virtual I/O ......
HMC Virtual slot DLPAR operation failed. Here are the virtual slot IDs that failed and the reasons for failure:
11 The dynamic logical partitioning operation failed.

The kernel on the lpar logs nothing.

When ran by the hmc gui, I get errors like this in the trace log on the lpar:
# rpttr /var/ct/IW/log/mc/IBM.DRM/trace | perl -ne ' if ( /\|(.+)\|/ ) { $a=$1; $a =~ s/\.+//g; print $a;} ' | perl -pe 's/[^7,^3]8/\n/g;'

The kernel logs nothing.

Why is it trying to run 'ioscli lsmap'? Isn't that only available for AIX?

I suspect this may be caused by an old hmc version. We run version
4.5.0-20050629.1. Does anyone know if there is a fix for bugs like
this in a later version?

Is it possible to update the HMC, for example to 5.x.something without
updating (read boot) the managed systems as well?
