Apparently it does work.  I put the lines the lines:
options         SYSVMSG
options         SYSVSEM
options         SYSVSHM
into my config file and the recompiled the 1.3.3 kernel.  Mesa-3.0 and
Unixdoom work perfectly now, and they use MIT-SHM.  ipcs also shows that
SysV IPC is enabled and that those programs are using shared memory.

BTW.  gcc optimization breaks r_data.c in Unixdoom.

Well, apparently they work in 1.3.3.  I see that some changes have been
made in -current (I can't find *any* SysV IPC related stuff in
arch/pmax... it's all probably been moved into arch independant place or
something)  Anyways, I expect IPC to work in -current as well.
