I am told that you *can't* run older Linux and AIX in a pSeries LPAR, so that's not really an issue. They won't run. > Does this make sense?

Watch the Intel Virtualization Technology (IVT) space and AMD's Pacifica technology. They will have SIE-like virtualization, providing the desired isolation and eliminating the need to modify the operating system. They won't, however, have support for 2nd level hypervisors.
