You should be able to set these via /boot/loader.conf which will let you
just use a GENERIC kernel. Run:
sysctl kern.ipc
to find the OID names and then just put eg:
kern.ipc.msgmnb=8192
into loader.conf (plus all the other tunables you want to change) and
reboot. For the gory details, look at /usr/src/sys/kern/sysv_msg.c --- I
can't find any actual documentation mentioning these OIDs but my reading
of the code suggests that is how it is meant to work.
Cheers,
Matthew
