What about a SAS LPAR?  We have an LPAR that primarily is used for
SAS.  We have the the LPALIB in LPA there.  All of the modules except
one are 31 bit.  It looks like about 13M of modules, so when running
many concurrent SAS jobs (which this LPAR does at times) the real storage
savings isn't trivial.  This is one of our smallest LPARs when it comes
to real storage (1G).

On the other hand, losing 13M of virt private above the line is trivial.
