So it isn't just one cpu type that fails.
Is there software running (most likely of the server variety) already
that may use up various shared resources that prevents postgres from
allocating what it needs? I'm referring to the sysctl options that you
would normally increase so you can use some of the larger settings in
postgres buffers etc. Something else may already be using most of these
resources.
Do you have the option of being able to stop any of these services for a
few minutes to test if this is the case?

Shouldn't matter if you aren't trying to allocate the resources but do
all the failing machines have more than 4GB RAM?

Try starting it with pg_ctl directly instead of using the script - the
script may recieve and hide some startup output that you will see on the
terminal if you run pg_ctl directly.
