Patrick,

I've only done a very quick search, but I found some newer documentation 
that might provide some clues. There's a "redpiece" that got published 
recently here:

http://www.redbooks.ibm.com/redpapers/pdfs/redp4131.pdf

Starting on page 5 there's a brief section on HMC configuration. There are 
a couple individuals listed at the end of the redpiece, and you might wish 
to drop them a line if you're still stuck. One thing I notice is they say 
"z900 GA2," and that's very specific language.  One of the big new 
features on the GA2 models was support for the PCICA, so that seems to 
make some sense as to why there might be that statement about the LPAR 
configuration.  Perhaps you have a GA1 or GA3 system?  (I think the GA2 
z900 was basically a microcode change from GA1.  The GA3 z900 models are 
in the 2xx series -- these are the "turbo" models.)

I also found this z900 Linux z/VM crypto performance report:

http://www.vm.ibm.com/perf/reports/zvm/html/crypto.html

which makes for an interesting read.  It looks like the crypto hardware 
does give a pretty good boost to Linux on z900 with PCICC, so I shouldn't 
have been so lukewarm.
