(I believe SYSVMSG is in GENERIC by default). 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.
