Unfortunately, no.  This isn't going to happen.  TORQUE's "node hello"
protocol was changed incompatibly very early in its development.  The
reverse won't work either, TORQUE pbs_server won't talk to openpbs mom.

You'll need to downgrade the ia64 box to openpbs, or upgrade the rest of
the cluster to TORQUE.  And I don't think old openpbs mom will work
correctly on newer linux distros.
