Well, we had similar problems on Solaris 5.6 some time before.
I think we had to add the following lines to /etc/system to make
it work:

forceload: sys/semsys
forceload: sys/shmsys

So we have the following lines added to /etc/system, although
I am no longer clear about what of these was necessary to start
postgres:

forceload: sys/semsys
forceload: sys/shmsys
set shmsys:shminfo_shmmax=268435456
set shmsys:shminfo_shmseg=20
set semsys:seminfo_semmap=250
set semsys:seminfo_semmni=500
set semsys:seminfo_semmns=1024
set semsys:seminfo_semmsl=500
set semsys:seminfo_semmnu=500
set semsys:seminfo_semume=100
set semsys:seminfo_semmni=200
