Jesus,
one possibility is to configure TCP/IP on the HPS. Then you can run
every standard PD-version of PVM the very day it is released. But this
is not optimal for low latency.
As you mentioned IBM offers a tuned version for the HPS. May be your 
information sources are not up to date. The youngest and finest :-)
version of PVMe is based on PVM 3.2.5.
I have attached an excerpt from an announcement I found today on
an IBM Gopher:

" IBM AIX PVMe(TM) Version 1 Release 2 and Release 3 are
high-performance implementations of the popular Parallel Virtual
Machine* (PVM) 3.2.5 interface that offer a migration path for
customers with IBM 9076 Scalable POWERparallel Systems(TM) configured
with the High Performance Switch.  Applications written in the PVM
language can be ported easily to IBM 9076 Scalable POWERparallel
Systems. "

Enjoy,
